Mitigation of Underslung Engine Induced Rail Coach Floor Vibration
Authors: Kumar Mukesh
Published: April 2024

The underslung arrangement consists of a 500kVA (kilovolt amperes) diesel generator set mounted below a railway passenger coach. To meet stringent vibration requirement in passenger compartment, dual vibration isolation arrangement is proposed for underslung arrangement. Such type of arrangement provides a high degree of isolation from engine induced vibration. Performance of dual stage isolation depends on stiffness and mass ratio of genset mass to intermediate bracketry mass. High vibration excitations are observed on rail coach floor during testing of baseline design. These vibration levels are more than rail prescribed limits and passenger can easily feel these vibrations. Study of dual stage (2 degree of freedom) isolation system frequencies and transmissibility is performed. Root cause for existing system is assessed through vibration transmissibility analysis. Modal analysis was performed to understand mode shapes and interaction between the mounting structure and isolators. Assessment shows that existing isolation system bracket modes are within engine exciting frequency range hence it amplifies vibrations. Vibration transmissibility sensitivity with respect to mass and stiffness is studied to get combination of mass and stiffness such that frequencies will be away from the engine operating frequencies. Based on analysis, overall design was improved to meet vibration requirements. Proposed solution to mitigate the vibration issue was validated with experimental measurements. Paper highlights a common mistake that most of the studies consider foundation as rigid body; in actual application detailed system level study and foundation stiffness plays important role. This paper gives analytical lead design guidelines to implement dual level isolation system for rail, marine, industrial etc. applications.

Authors: Courtney Amy , Crosby Charles , Miller Bruce , Osterhout Aaron , Walker James , Gondek Jonathon
Published: April 2024

There are established federal requirements and industry standards for frontal crash testing of motor vehicles. Consistently applied methods support reliability, repeatability, and comparability of performance metrics between tests and platforms. However, real world collisions are rarely identical to standard test protocols. This study examined the effects of occupant anthropometry and passive restraint deployment timing on occupant kinematics and biomechanical loading in a moderate-severity (approximately 30 kph delta-V) offset frontal crash scenario. An offset, front-to-rear vehicle-to-vehicle crash test was performed, and the dynamics of the vehicle experiencing the frontal collision were replicated in a series of three sled tests. Crash test and sled test vehicle kinematics were comparable. A standard or reduced-weight 50th percentile male Hybrid III ATD (H3-50M) or a standard 5th percentile female Hybrid III ATD (H3-5F) was belted in the driver’s seating position. In the crash test, the frontal airbag and lap and shoulder belt pretensioners deployed on commands from the vehicle’s airbag control module (ACM). In the sled tests, deployments were commanded with either similar timing or 12 milliseconds earlier. Small, measurable differences in occupant kinematics and biomechanical loading were observed. All biomechanical metrics were low compared to injury assessment reference values (IARVs), consistent with the moderate severity of the tests. The variations in parameters in these tests did not result in suboptimal interactions with restraints, such as submarining, belt webbing migration, or bottoming-out of the airbag resulting in direct occupant loading to the steering wheel. These results indicate that the variations in occupant anthropometry and restraint deployment times investigated did not substantially alter the low risk of serious injuries.
A Simulation Model for an Online Corrective Look-Ahead Road Profiling System (CLARPS) for Active Suspension Applications
Authors: Morison Dane , Mynderse James
Published: April 2024

Online road profiling capability is required for automotive active suspension systems to be realized in a commercial landscape. The challenges that impede the realization of these systems include a profiler’s ability to maintain an optimal resolution of the oncoming road profile (spatial frequency). Shifting of the profile measurement frame of reference due to body motion disturbances experienced by the vehicle also negatively impacts profiling capability. This work details the early development of a corrective look-ahead road profiling system (CLARPS) and its control logic. The CLARPS components are introduced and additional focus will be given to the development of the angle generating function (AGF) and how it drives the ability of the system to optimize look-ahead viewing angles for the best spatial frequency resolution of a road profile. The CLARPS simulation environment is demonstrated with numerical comparison of simulated road profiles at varying vehicle speeds.

Authors: Du Canjie , Yin Zhihong , Xia Zhao , Wang Weiwei , Shangguan Wen-Bin
Published: April 2024

This paper presents an adaptive H2/H∞ control strategy for a semi-active suspension system with unknown suspension parameters. The proposed strategy takes into account the damping force characteristics of continuous damping control (CDC) damper. Initially, the external characteristics of CDC damper were measured, and a forward model and a back propagation (BP) neural network inverse model of CDC damper were proposed using the measured data. Subsequently, a seven-degree-of-freedom vehicle with semi-active suspension system and H2/H∞ controller was designed. Multiple feedback control matrices corresponding to different sprung mass parameter values were determined by analyzing time and frequency domain performance. Finally, a dual observer system combining suspension state and parameter estimation based on the Kalman filter algorithm was established. The estimated parameter was used to determine feedback control matrix, while the observed states were used to calculate the desired damping force of CDC damper. Simulation results show that the proposed adaptive H2/H∞ control strategy can estimate sprung mass value in real time, enabling the switching of feedback control matrix based on the estimated results. Consequently, vehicle ride comfort is enhanced while handling stability is not excessively deteriorated. Compared to real-time calculation of control parameters method, the proposed control strategy reduces computations and ensures robustness of semi-active suspension systems.
An Experimental Study on Camshaft Impact Noise by Dynamic Coupling of Valve Train and Chain System
Authors: Park Keychun , Kang Sungwoo , Kim Sukzoon
Published: April 2024

To improve the fuel efficiency and satisfy the strict emission regulations, the development of internal combustion engine gets more complicated in both hardware and software perspectives, and the margins for durability and NVH quality become narrower, which could result in poor NVH robustness in harsh engine operating conditions. In this paper, we investigate experimentally the camshaft impact noise mechanism relating the valve train and timing chain forces to detailed motion of the camshaft and the chain tensioner. After the initial investigation of identifying the impact timings and specific engine operating points when the noise occurs, the camshaft orbital motion inside of the sliding bearing is measured and visualized with the proximity sensors with calibration after sensor mounting, in addition to the chain tensioner movements. It is shown that the impact noise occurs at the event of the abrupt change of camshaft orbital motion, which results from the combined resultant force of valve train and timing chain forces. As the valve timing has significant effects on the breathing and combustion efficiency sequentially, only the timing chain force on the camshaft is modified in a way to reduce the abrupt change of movement of the camshaft. In conclusion, the mechanism of camshaft impact has been identified with the proper visualization of the camshaft movement together with the tensioner force-displacement diagram in problematic engine operation condition.
A Visual SLAM Based-Method for Vehicle Localization
Authors: Hsu Chih-Yuan , Lin Nong-Hong
Published: April 2024

One of the main challenges of autonomous driving is to integrate different modules, such as perception, planning, control, and communication, that work together to enable the vehicle to drive safely and efficiently. A key module of autonomous driving is the vehicle localization system, which estimates the vehicle's position in the environment, and provides guidance for the optimal route. The vehicle localization system is essential for ensuring the safety of autonomous driving. This paper proposes a vehicle localization method based on visual simultaneous localization and mapping (SLAM) using a monocular camera. The method captures images of the environment with a monocular camera and extracts ORB (Oriented FAST and rotated BRIEF) features from them. It then tracks the features across the images and constructs a sparse map of the scene. The map is used to estimate the vehicle's pose, which is the position and orientation of the vehicle, in local coordinates. The pose is then rescaled and converted to geographic coordinates. The method is tested and evaluated on outdoor datasets. The average localization error is less than 0.5 meter. The method is suitable for low-cost applications.
State-of-Charge Estimation for LiFePO4 Batteries with Adaptive State Update in Specific OCV Ranges Using Adaptive Extended Kalman Filter
Authors: Sandrabyna Mallikarjuna , Patil Akshata
Published: April 2024

Lithium-ion batteries are the ubiquitous energy storage device of choice in portable electronics and more recently, in electric vehicles. However, there are numerous lithium-ion battery chemistries and in particular, several cathode materials that have been commercialized over the last two decades. In recent time several automakers have followed trend by announcing their own plans to move their EV production to LFP, due to its high intrinsic safety, fast charging, and long cycle life and cobalt free batteries as well as avoiding other supply chain constrained metals like nickel. Accurate estimation of the state-of-charge (SOC) is crucial for efficient and safe battery applications. However, existing SOC estimation methods (coulomb count, SOC-OCV methods) fail to provide accurate SOC estimation for LFP batteries that have a flat voltage-SOC relationship, and these present model-based methods can be ascribed to their inability to simultaneously accommodate the differences in voltage characteristics between different open-circuit-voltage (OCV) ranges. To address this limitation, offline three RC equivalent circuit model is used to identify OCV and other battery model parameters. Then, the parameters of the extended Kalman filter are adaptively estimated according to the innovation residual error and updated in different OCV ranges, which are distinguished based on the identified OCV. While conventional methods fail to converge, the proposed method ensures both high accuracy and stability, with a maximum absolute error of < 3%. The viability of the proposed method is further verified using data collected from real battery systems.
A Percipient Analysis of Jaguar I-PACE Electric Vehicle Energy Consumption Using Big Data Analytics
Authors: Dutta Nilabza , Evans David , sapte Atharva
Published: April 2024

Vehicle efficiency and range, along with the DC charging speed, are deemed as the most important criteria for an electric vehicle currently. The electric vehicle energy consumption is impacted by the change in temperature along with the driving style and average speed of a customer, all other factors being constant. Hence understanding the patterns and impact of different aspects of an EV range & charging speed is crucial in delivering an electric vehicle with robust efficiency across all weather conditions. In this paper we have analysed vehicle parameters of global Jaguar I-PACE customer data. We present and analyse the collated big data of around 50,000+ unique vehicles with a data aggregate of well over 482 million km. In moderate ambient conditions the analysis indicated a good correlation with 50th to 75th percentile drivers’ energy consumption to the EPA label figure. The EPA hot and cold ambient tests also compare well but the correlation is sensitive to long and short trip distances. The cumulative data of the global fleet, for 75th percentile customers, shows that the total consumption of the vehicle increases by 81% and 47%, from the median energy consumption at 20°C, at -10°C and 0°C respectively. Similarly, the global fleet energy consumption, for 75th percentile customers, increased by 7% and 31% respectively, from the median energy consumption at 20°C, at 30°C and 40°C respectively. The paper then deep dives into data bins analysing the consumption sources for certain key drive and ambient scenarios.
A Study on Correlation between Micro Structure of Porous Sound Absorbing Materials and Sound Absorption Performance Using CT
Authors: Kim Taeyoon
Published: April 2024

One of the five major performances of vehicles, NVH(Noise, Vibration, Harshness), has recently emerged in electric vehicles, again. And, front loading NVH simulation is essential to respond nimbly to automotive industry these days. However, the two components of the simulation, mathematical sound absorption modeling equation, and the acoustic parameters, the input factor, is requiring improvement because of lack of robustness. In this study, we tried to strengthen, standardize, and refine the connectivity between micro (fine structure) and macro (acoustic parameter-related physical properties) characteristics, and improve the consistency with actual NVH performance. As a porous polymer material, polyurethane foam, which is widely used for the interior and exterior of automobiles, is treated as a target material. It is expected that further refining of the correlation between three-dimensional microstructure properties of foam such as pore, throat, strut, window, etc. and acoustic parameters such as air flow resistivity and porosity, etc., can result in more precise sound absorption performance in the modeling formula.
Development of Noise Diagnosis and Prediction Technology for Column-Based Electric Power Steering Systems Using Vehicle Controller Area Network Data
Authors: Chung Soo Sik
Published: April 2024

The steering system is a critical component for controlling a vehicle's direction. In the context of Advanced Driver Assistance Systems (ADAS) and autonomous vehicles, where drivers may not always be actively holding the steering wheel, early detection of precursor noise signals is essential to prevent serious accidents resulting from the loss of steering system functionality. It is therefore imperative to develop a device capable of early detection and notification of steering system malfunctions. Therefore, the current study aimed to quantify the noise levels generated within the Column-based Electric Power Steering (C-EPS) system of a D-segment sedan. To this end, we measured the uniaxial acceleration in nine noise-generating areas while simultaneously collecting data from three Controller Area Network (CAN) sources that are directly related to steering operation. The results indicated that we have successfully developed a meaningful machine learning model by analyzing the correlation between steering noise acceleration and CAN data. Altogether, we have designed an algorithm that is capable of predicting steering system malfunctions when abnormal noise acceleration occurs, thereby enhancing accident prevention capabilities.

Review of Using Shear Walls and Bracings for Seismic Strengthening of High-Rise RC Structures
Authors: Aparna Nishtala  , Ajay Radke
Published: April 2024

This review explores the seismic resistance of high-rise buildings through the implementation of shear wall and steel bracing systems. The use of reinforced concrete (RC) buildings with shear wall systems and steel structures with concentrated steel bracing systems has become increasingly common to mitigate seismic effects. However, the response of these systems to seismic loads varies due to differences in structural design and response factor values. Additionally, the presence of asymmetrical building designs poses a potential risk during earthquakes, necessitating a thorough examination of both new and old structures. By analyzing the dynamic properties and influencing factors of irregular RCC buildings with shear walls, this research aims to assess the impact of shear walls on factors such as base shear, torsion, story displacement, and drift. Furthermore, the study investigates the effectiveness of steel bracing systems in enhancing the performance of high-rise buildings under wind and seismic loading conditions. Different bracing configurations are evaluated to determine their ability to reduce lateral displacements and improve structural strength and stiffness. The findings will provide valuable insights into optimizing the location and design of bracing systems for enhanced structural resilience against seismic and wind forces while considering both economic and effectiveness factors.

PAG-INDO ‘SA LINAWNGAN NA SAMA: A PHENOMENOLOGICAL STUDY ON THE LIVED EXPERIENCES OF TEACHERS OF SAMA LEARNERS
Authors: PEREZ MICHELLE P.
Published: April 2024

In the heart of Davao Gulf in Southeastern Mindanao lies the pristine Island of Samal - the homeland of Sama indigenous group and have lived there since the beginning of time. The Island Garden City of Samal (IGaCoS) can be reached by ferry boat from Davao City. Learners of any indigenous group are highly influenced by their own distinct environments and experiences, the explicit exposure of Sama learners to their own Mother Tongue – Sama Language is beneficial in their pursuit of linguistic competence albeit furthers the maintenance of their cultural heritage. Hence, in 2016, the Department of Education implemented the IPED program that aims to teach children the history and the language of Sama. The Department of Education Island Garden City of Samal recognize the importance of providing culturally appropriate learning resources in the mother tongue for children of Indigenous Peoples such as the Sama. This will ensure that no Sama children are left behind as the K-12 Mother Tongue-Based Multilingual Education (MTB-MLE) system is implemented nationwide. The Sama have an estimated population of 32,000 and live in Island Garden City of Samal. Teachers are facing problems in the implementation of IPEd Program like lack of learning resources and lack of knowledge on indigenous knowledge systems and practices (Olpindo, 2018). In this context, the core of this study is the experiences of teachers handling Sama Learners in terms of their pedagogy focusing on communication classes. Universities produce educators that fill positions in the various supply chains of the nation’s education systems. These educators over the last four decades have emerged from their universities with very little exposure to Indigenous insights and then they inadvertently replicate either or at worse illegitimate or illinformed Indigenous content in their disciplinary field. All children are on a continuum of learning. It is essential that teachers find out where each of their students is on the continuum by developing knowledge of individual students’ learning levels and needs. (Perso, Thelma.

BALANCE OF TRADE, EXCHANGE RATE AND ECONOMIC GROWTH IN NIGERIA
Authors: Baghebo Michael , Mienebimo Kingdom
Published: April 2024

This study delved into the relationship between the balance of trade, exchange rates, and economic growth in Nigeria. Utilizing annual time series data spanning from 1981 to 2021 sourced from the Central Bank of Nigeria (CBN) statistical bulletin and the National Bureau of Statistics (NBS), the investigation employed a Heteroskedasticity Model. Within this framework, GARCH, an expanded version of ARCH, and the Exponential Generalized Autoregressive Conditional Heteroskedasticity (EGACH) were applied. The findings revealed that both trade balance and exchange rates exhibited heightened sensitivity to adverse news, indicating that uncertainties surrounding exchange rates significantly contributed to fluctuations. Moreover, the ARCH effects initially observed in the balance of trade and exchange rates were completely mitigated by the considered heteroskedastic models. Furthermore, the study identified a negative and statistically significant impact of the balance of trade on economic growth. Similarly, exchange rates were found to exert an undesirable significant influence on economic growth in Nigeria. This suggests that unfavorable changes in the Nigerian naira tend to exacerbate its volatility. Notably, while the relationship between trade balance and economic growth was positive, it did not reach statistical significance. In conclusion, the study underscores the critical role of external demand in driving economic growth in Nigeria, particularly highlighting the stimulative effect of a strong depreciation of the domestic currency. As a recommendation, the government is urged to adopt export-driven policies aimed at bolstering trade balance, fostering export, particularly of primary products, to attract foreign exchange inflows and foreign investment, thereby spurring economic growth in Nigeria.
Interest Rate and Investment Nexus in Nigeria
Authors: Apere ThankGod , Akarara Ebierinyo
Published: April 2024

Since “interest rate policy is one of Nigeria's most contentious laws and has attracted the attention of several academics, it is unknown how it will affect the country's investment base. Thus, between 1981 and 2015, this study looked at how interest rates affected investment in Nigeria. The 2016 Statistical Bulletin of the Central Bank of Nigeria included secondary data that were gathered. In order to examine the data, the study calculated the Johansen Multivariate Co-integration model and the Error Correction Model (ECM). The co-integration test results indicate that there is a long-term link between investment, as measured by gross fixed capital formation (GFCFG), and the proxies for interest rates (MLR, MPR, and SAVR).” According to the “ECM conclusion, MLR and MPR have a statistically significant negative impact on investment in Nigeria. Although SAVR increases investment, this effect is not statistically significant. Additionally, according to the ECM, 40% of the disequilibrium from the previous year would be addressed in the present time. The conclusion of this study is that high interest rates discourage investment. To encourage investors to access money, it is suggested, among other things, to lower the lending and monetary policy rates to a single digit. This would result in the nation's economy growing.”

The data was collected with a structured interview schedule from two groups of villages namely climate-smart and non-climate-smart villages randomly selected 120 respondents from four blocks of Karnal and Kaithal districts. The constraints were divided into three categories i.e., economic constraints, socio-personal constraints, and technological constraints. The analysis revealed that technical constraints such as lack of awareness about climate-smart agricultural practices, lack of training, and complexity of climate-smart practices were the major barriers to the adoption of climate smart agricultural practices among the farmers of non-climate smart villages whereas, economic constraints such as increased cost of paddy production, higher initial investments in inputs and lower paddy yields were the most serious constraints faced by farmers in climate smart villages. Furthermore, it was observed that, while there was not much difference in socio-personal and economic constraints faced by both groups of respondents, however, respondents from non-climate smart villages faced a significantly higher degree of technical constraints as compared to the respondents from climate smart villages.

Este trabalho visa aprofundar o entendimento sobre a potencial dificuldade que os executivos, no varejo, podem apresentar em equilibrar as demandas por resultados de curto e longo prazo. A pesquisa tem como objetivo analisar como o paradoxo curto-longo prazo se manifesta e influencia o processo decisório de executivos do varejo brasileiro. Foi realizada uma revisão bibliográfica sobre os temas: Papel Econômico do Varejo, Liderança e Paradoxos Estratégicos, e Tomada de Decisão. O método utilizado foi qualitativo, de natureza exploratório–descritivo. Foram coletados dados empíricos através de 12 entrevistas semiestruturadas, com executivos de empresas brasileiras do varejo alimentar. O tratamento dos dados foi através da Análise de Conteúdo, sendo identificadas categorias-chave e subcategorias. Os principais resultados mostram que alguns temas são percebidos como processos interligados de forma dinâmica e complementar. Ficou evidente a percepção da importância da gestão focada nos stakeholders, em que todas as partes interessadas são incluídas no processo de análise de possibilidades, tomada de decisão e elaboração dos planos de longo prazo, como tendo grande potencial de influência na gestão do paradoxo curto e longo prazo. Este estudo contribui com insights sobre os aspectos da organização e elementos que influenciam para um maior equilíbrio da gestão do paradoxo curto longo prazo.
