The primary gasotransmitters and their respective donors in the mission of vision (eye health): a comprehensive overview
Authors: Mir Jan , Maurya R
Published: November 2020

Nitric oxide (NO) along with Carbon monoxide (CO) and Hydrogen Sulphide
(H2S) are biologically significant gaseous molecules generally called as
“gasotransmitters”. At a concentration higher or lower than optimum
value may result in toxicity or malfunctioning of mammalian tissues.
Soon after the acknowledgment of NO as multifunctional bio-signalling
molecule in 1987, many interesting implications of this field emerged
out. Meanwhile, several studies have proven the NO-biosynthetic pathway
responsible for normal functioning of eye. High intraocular pressure
(IOP) has been suggested as the main risk factor in this context and
collaborative approach with nitric oxide releasers is said to control
IOP and hence the relation with glaucoma. Similar miracles were
reflected from several other naturally produced gaseous molecules,viz.,
CO and H2S after year 1990. The biological roles of both these molecules
are now widely accepted and in the current era investigations focused
mainly with development of efficient CO and H2S releasing compounds. CO
and H2S donors are also said to help in normalising IOP like NO.
Therefore the trio-gasotransmitters have collective relation with the
ophthalmic homeostasis in association with nervous control. On one hand,
the antimicrobial efficiency of these three molecules is widely known
and on the other hand, their collaborative key-role in ocular nerve
functioning makes it remarkable to state here that their donors are
supposed to act as a shield for both the infectious as well as the
non-infectious eye defects.

Authors: Abdel-salam Emad , NOUH Mohamed , Azzam Yosry
Published: November 2020

The helium burning phase represents the second stage that the star used
to consume nuclear fuel in its interior. In this stage, the three
elements carbon, oxygen, and neon are synthesized. The present paper has
two folds, the first is to develop an analytical solution to the system
of the conformable fractional differential equations of the helium
burning network, where we used for this purpose the series expansion
method and obtained recurrence relations for the product abundances i.e.
helium, carbon, oxygen, and neon. Using four different initial
abundances, we calculated 44 gas models covering the range of the
fractional parameter with step . We found that the effects of the
fractional parameter on the product abundances are small which coincides
with the results obtained by a previous study. Second, we introduced the
mathematical model of the neural network (NN) and developed a neural
network algorithm to simulate the helium burning network using its
feed-forward model that is trained by the back propagation (BP) gradient
descent delta rule algorithm. A comparison between the NN and the
analytical models revealed very good agreement for all gas models. We
found that NN could be considered as a powerful tool to solve and model
nuclear burning networks and could be applied to the other nuclear
stellar burning networks.

Toward Using Tire-Road Contact Stresses in Pavement Design and Analysis
Authors: De Beer Morris , Maina James W. , van Rensburg Yvette , Greben Jan M.
Published: November 2020

Optimization of road pavement design, especially close to the surface of the pavement, requires a more rational approach, which will inevitably include modeling of truck tire-road contact stresses. Various road-surfacing failures have been recorded as evidence that the traditional road pavement engineering tire model idealized by a single uniformly distributed vertical contact stress of circular shape may be inadequate to properly explain and assist in the design against road surface failures. This article therefore discusses the direct measurement of three-dimensional (3D) tire pavement contact stresses using a flatbed sensor system referred to as the “Stress-In-Motion” (SIM) system. The SIM system (or device) consists of multiple conically shaped steel pins, as well as an array of instrumented sensors based on strain gauge technology. The test surface is textured with skid resistance approaching that of a dry asphalt layer. Full-scale truck tires have been tested since the mid-1990s, and results show that 3D tire contact stresses are nonuniform and that the footprint is often not of circular shape. It was found that especially the vertical shape of contact stress distribution changes, mainly as a function of tire loading and associated tire inflation pressures. In overloaded/underinflated cases, vertical contact stresses are the highest toward the edges of the tire contact patch. Higher inflation pressures at lower loads, on the other hand, result in maximum vertical stresses toward the center portion of the tire contact patch. These differences in shape and magnitude need to be incorporated into modern mechanistic-empirical road pavement design tools. Four different idealized tire models were used to represent a single tire type to demonstrate effects of tire modeling on the road pavement response of a typical South African pavement structure incorporating a relatively thin asphalt surfacing. Only applied vertical stress was used for the analyses. It was found that the fatigue life of the road surface layer can be reduced by as much as 94% and strain energy of distortion be increased by a factor of 2.8, depending on the characteristics of the tire model input selected for road pavement design and analysis.
Investigations of Road Wear Caused by Studded Tires
Authors: Gültlinger Johannes , Gauterin Frank , Brandau Christian , Schlittenhard Jan , Wies Burkhard
Published: November 2020

The use of studded tires has been a subject of controversy from the time they came into market. While studded tires contribute to traffic safety under severe winter conditions by increasing tire friction on icy roads, they also cause damage to the road surface when running on bare roads. Consequently, one of the main challenges in studded tire development is to reduce road wear while still ensuring a good grip on ice. Therefore, a research project was initiated to gain understanding about the mechanisms and influencing parameters involved in road wear by studded tires.

A test method using the institute's internal drum test bench was developed. Furthermore, mechanisms causing road wear by studded tires were derived from basic analytical models. These mechanisms were used to identify the main parameters influencing road wear by studded tires. Using experimental results obtained with the test method developed, the expected influences were verified. Vehicle driving speed and stud mass were found to be major factors influencing road wear. This can be explained by the stud impact as a dominant mechanism. By means of the test method presented, quantified and comparable data for road wear caused by studded tires under controllable conditions can be obtained. The mechanisms allow predicting the influence of tire construction and variable operating conditions on road wear.
An Investigation into Wheel Sinkage on Soft Sand
Authors: Hathorn G. N. B. , Blackburn K. , Brighton J. L.
Published: November 2020

Sinkage is an empirically significant factor in vehicle performance as it can result in an immobile vehicle or significant environmental damage. Bernstein first proposed a pressure-sinkage relationship in 1913, and subsequent work by Janosi and Hanamoto and Hedegus concluded that longitudinal wheel slip also plays a role in sinkage. Shinone, Nakashima, Takatsu, Kasetani, and Matsukawa identified a linear relationship between slip and sinkage on a lightly loaded tire (980 N). In this study, the effects of vertical wheel load, longitudinal wheel slip ratio, and tire inflation pressure on wheel sinkage on loose sand were investigated to relate sinkage to a vehicular operating condition. The test program in this study was conducted using the Cranfield University Single Wheel Tester (SWT) on loose, desert-like sand in the Cranfield Off-Road Dynamics facility soil lane. The SWT uses a closed loop servo-controlled hydraulic actuator to actively control vertical wheel load and twin hydraulic motors to actively control wheel speed. The SWT apparatus is mounted on an independent prime mover tractor unit, which controls forward speed. True forward speed is continuously measured against a fixed reference point and used to calculate the required wheel speed in real time to give the desired slip profile. A series of controlled load tests were conducted using a Goodyear G90 tire on a dry desert sand material. Four discrete inflation pressures (0.69, 1.38, 2.07, and 2.76 bar [10, 20, 30, and 40 psi] and four vertical wheel loads (1, 2, 3, 4, and 5 kN) were chosen to represent the operating range of the tire. Each test run consisted of a continuously decreasing sweep of longitudinal wheel slip ratio (the slip ratio was controlled to decrease linearly from 85% [driven] to −15% [braked]). Although a near-linear increase in sinkage was identified for wheel slip ratios greater than 10%, as Shinone et al. also found, the overall relationship between slip ratio and sinkage was found to be nonlinear.
Effectiveness of Tetrahedral Finite Elements in Modeling Tread Patterns for Rolling Simulations
Authors: Surendranath Harish
Published: November 2020

Generating structured hexahedral finite element meshes on tread patterns is a challenging and laborious task due to the complex pattern geometry. However, creating good quality tetrahedral meshes on these geometries is relatively straightforward and can be fully automated. Despite the convenience and time saving, analysts have long avoided tetrahedral elements because of inadequate contact stress accuracy, which is critical for pattern wear prediction. Recent advances in contact formulation has vastly improved the accuracy of contact stresses predicted by tetrahedral meshes. This article presents a comparative study between the results predicted by tetrahedral and hexahedral meshes under slow rolling conditions. Comparisons are presented for footprint solution quantities such as contact stresses as well as global solution quantities such as residual aligning torque.
Tire Transient Lateral Force Generation: Characterization and Contribution to Vehicle Handling Performance
Authors: Wei Terence , Dorfi Hans R.
Published: November 2020

Tire force generation is often described in terms of a steady-state force response, which is considered independent of time and a function of the kinematic roll conditions such as slip angle. In addition to the steady-state response, the tire also exhibits a time-dependent transient force response, which in the lateral direction is a delay in the buildup of the cornering force. This delay is often characterized by the so-called tire relaxation length (RL) (Ly), a tire performance characteristic often thought to have a strong effect on handling performance. The definition and mechanistic interpretation of tire lateral RL is discussed, and different methods for measuring and interpreting lateral RL are compared. The measurement methods include different types of flat belt as well as static stiffness measurements. Because of different levels of measurement uncertainty, the repeatability and benefits of the different measurement methods are demonstrated. To determine the effect of including tire transient response in tire/vehicle system models, a handling study was performed. The study included a series of CarSim handling simulations with tires of different transient force and moment characteristics as well as an analysis of outdoor subjective handling ratings. The results show the relatively small contribution of tire transient characteristics to vehicle handling performance compared with the tire steady-state force response.
Efficient In-Plane Tire Mode Identification by Radial-Tangential Eigenvector Compounding
Authors: Tsinias Vasilis , Mavros George
Published: November 2020

Tire modal testing is frequently used for validation of numerical tire models and identification of structural tire model parameters. Most studies focus primarily on in-plane dynamic tire behavior and adopt the approach of the fixed boundary condition at the wheel center. Here, an identification method of in-plane tire dynamics was developed for the case of a free tire-rim combination. This particular case is important when the aim is to construct a full tire model, capable of predicting ride and noise, vibration, and harshness involving the whole vehicle, all from modal testing. Key attributes of the proposed approach include ease of implementation and efficient processing of measurements. For each type of excitation, i.e., radial and tangential, both radial and tangential responses were recorded. Compounding of the corresponding radial/tangential eigenvectors, which, in the context of the present work, refers to expressing the motion of the tire belt as a combination of the radial and tangential responses, results in smooth mode shapes that were found to agree with those published in other analytical and experimental studies.

Authors: Cai Yongzhou , Zang Mengyan , Duan Fuyao
Published: November 2020

The finite element (FE) model of a tire to simulate tire blowout is developed, the effectiveness of which is validated by the tire blowout test. Then, a simplified FE model of a vehicle that integrates the tire model is established. The vehicle responses to tire blowout are analyzed under the situation of no steering and braking behavior on the vehicle. Finally, some meaningful results, such as the trajectory, yaw velocity of the vehicle, and the forces acting on the tires, are obtained. This study provides the foundation to further investigate the handling stability and control strategy of a vehicle when a tire blowout occurs during normal vehicle operation.
Influence of Tire Operating Conditions on ABS Performance
Authors: Sivaramakrishnan Srikanth , Singh Kanwar Bharat , Lee Peter
Published: November 2020

During its normal service life, a tire is subjected to large variations in operating conditions, such as ambient temperature, inflation pressure, and changes in tread depth. The longitudinal force response of the tire changes significantly because of each of these operating conditions. This, in turn, would directly influence the performance of the antilock braking system (ABS) installed in a vehicle. Current ABS systems are tuned for a vehicle with fixed operating thresholds that do not change. The objective of this study was to understand the influence of a tire's operating conditions on ABS efficiency and the extent of variation it can cause on stopping distance. This was done by obtaining longitudinal-slip characteristics for a given tire at various temperatures, inflation pressures, and tread depth through a traction trailer. These data were then used to simulate an ABS braking maneuver using a half-car vehicle model. The major reasons for the loss in stopping distance performance because of a drop in efficiency under each condition was then analyzed in detail. The latter part of this study explored the potential for improvement in stopping distance that could possibly be achieved through an intelligent ABS system that would use tire-sensed information, such as temperature, pressure, and tread depth to calculate essential tire characteristics in real time using an adaptive magic formula and change its tuning parameters accordingly.
Investigations on Winter Tire Characteristics on Different Track Surfaces Using a Statistical Approach
Authors: Wassertheurer Bernd , Gauterin Frank
Published: November 2020

The availability of reliable tire simulation models is necessary for performing accurate vehicle-handling simulations. Parameterizing of tire models, such as the Magic Formula (MF) tire model, means extensive measurement and complex fitting procedures. In addition, a general problem is that parameterized MF models are not simply adaptable to other track surfaces (e.g., dry, wet, or snowy tracks), which is a problem, especially for winter tire modeling. To face this drawback, a research project in cooperation between BMW and the Karlsruhe Institute of Technology, Institute of Vehicle System Technology, has been initiated.

The institute's internal drum test bench provides the opportunity to perform measurements on different track surfaces and various operating conditions. To identify main effects on tire performance and tire characteristics, comprehensive measurements on snow, ice, wet asphalt, and dry Safety-Walk surfaces have been carried out using three different winter tires.

Experimental designs have been worked out using the method of design of experiments (DoE) to reduce the number of measurements and to decrease measuring expenditure, especially on snow track surfaces. By using DoE, all statistic effects can be analyzed despite reducing the number of measurements.

Measurement data have been analyzed using extensive statistical methods. Thereby, effects on the tire characteristics have been empirically identified, and general predications will be presented in the article. We show identified main effects of track and ambient conditions on tire performance and tire characteristics. Furthermore, this article demonstrates the approach of using DoE to perform lean measurements as well as illustrates the realization of executing the measurements on different track surfaces on the test bench.

These results will also be a starting basis for establishing a novel empirical model for adopting tire characteristic curves and MF tire models on alternative road and ambient conditions.
