Published: January 2023

In the present work finite element analysis of foldable electric vehicle is carried out. With the use of finite element analysis, the magnitude of stresses and deflections at critical locations of the vehicle is evaluated. Dynamic analysis to simulate the vehicle behavior has also been carried out. The vehicle is proposed to accommodate a single passenger. The foldable vehicle is designed as per the regulations prescribed by the Automotive Resarch Association of India. Maximum vehicle speed of 25 kmph and dimensions in folded circumstances are the design constraints accounted for in the present work. Vehicle dimensions are computed using design constraints and the process mentioned in Automotive Industry Standard 049 (AIS-049). Materials for vehicle chassis, seat, hand rests, and centrally located telescopic support are steel 1018 and aluminum from speed and self-weight considerations. With the aid of the classical approach braking force, motor torque, wheel rpm, power, rolling resistance, and aerodynamic drag are calculated. Solidworks software is used for the preparation of computer-aided model. Finite element analysis of the foldable vehicle has been carried out to evaluate the static and dynamic stresses induced in the vehicle components. The meshing of the foldable vehicle is carried out using Ansys Workbench. From modal analysis, six mode shapes of the foldable vehicle are formulated, and corresponding frequencies and deflections are devised. A Mesh generator is used to mesh the foldable vehicle. The deflection and frequency magnitudes of the foldable vehicle evaluated are in good agreement with the experimental results available in the literature for similar materials.

Published: January 2023

An upright is the most crucial component of the suspension system of an All-terrain vehicle. It acts as a link for other component such as suspension arms, drive axle, steering tie rod, wheel hub, and brake calliper enabling a smooth comfortable ride. The upright has to withstand the entire force experienced during the dynamics of the vehicle before the energy is dampened by the coil-overs. The brake calliper is mounted on the upright and thus it has to withstand the forces generated during braking. Considering these factors, the design of the upright has to be highly efficient and done with utmost precision ensuring no or minimum failure. This paper outlines the design, analysis and optimization of the upright to be used in the ATV that will participate in BAJA SAE events of India and USA. The basic sketch necessary to design the upright is created in the form of a line diagram of the front geometry suspension system in Solid works. This geometry is then analysed using LOTUS software ensuring a near to perfect ride and handling. The 3D CAD model of the upright is designed in Solid works with respect to the front geometry of the suspension. The static structural analysis of the model is then performed on ANSYS mechanical followed by topological optimization of the model. Based on the results from this analysis, the improved CAD model of the upright has been designed and analysed. The main objective of this paper is to come up with a highly optimized design that ensures a high factor of safety while maintaining a lower weight. These optimizations proved to be helpful by reducing the weight of the component around 60 grams and increasing the factor of safety from 1.58 to 2.43.

Published: January 2023

The purpose of the study is to make quantitative and qualitative analyses on the Metal Matrix Composite (MMC). The MMC comprises aluminum alloy AA6061 as the matrix element and 5%, 10% and 15% by weight of silicon carbide particulate (SiCp) as the reinforcement material, before and after heat treatment. This investigation compares the mechanical properties and metallurgical characteristics of the MMC with the base material AA6061. In the present investigation, stir casting method is used for preparing samples of MMC. The produced composites were subjected to heat treatment to enhance their hardness. The influence of the weight composition of the reinforcement particles on the mechanical properties of the MMC is analyzed quantitatively. The mechanical properties such as tensile strength, impact strength and hardness were measured for quantitative analysis, while scanning electron microscope is used for qualitative analysis. The temperature of the furnace and the hardening time during the heat treatment process control the hardness exhibited by the composite materials. The percentage composition of reinforcements in the composite materials influences their mechanical properties. Based on the results, optimal material has been suggested for a wide range of applications. The proposed investigation indicates that if the heat treatment increases, then the microhardness of the MMC increases by 13.86%, 18.45% and 30.19%, respectively for 5, 10, and 15% by weight SiCp. It is also observed that the maximum tensile strength of MMC is 329 MPa at 10 % by weight of SiCp. Compared to the base material, it is a 12.5% increase in its tensile strength. Increase in the percentage composition of SiCp to 15wt. % reduced the impact strength by 13%. The scanning microscopy reveals that MMC having 10% by weight of SiCp has a medium-size grain structure.

Published: January 2023

The study examines the quality of friction stir welded joints made with butt joints on a metal matrix composite. In the composite, AA6061 is the matrix and silicon carbide is the reinforcement. Joints were made with three different pin profiles: circular, triangular and square. Macroscopic and microscopic images were used to qualitatively assess the joints. With the circular pin-profiled tool, the joints had distinctive onion ring patterns on their surface. Plasticized metal flows uniformly from the advancing side to the retreating side. While using triangular and square pin tools, weld spatters were formed along the retreating side of the joint. During the joining process, the plasticized material intermittently flowed. Inspection of the weld cross-section showed a major tunnel defect. The circular pin could not transfer materials that were not sufficiently plasticized. Plasticized material below the triangular pin tool was splashed by the tool pin edges. The bottom of the joint got enough weldment due to this. As a result, there were bind defects along the advancing and retreating sides of the joint. A square pin tool did not cause any defects in the weld joint. Because the tool pin had more edges, the weldment was deposited uniformly throughout the joint. Various zones of the joint showed grain restructuring. Using the circular pin profile tool, a noticeable plane separated thermo-mechanically and heat-affected zones. When using triangular and square pin tools, the three zones transitioned gradually. When using the square pin tool, the grain size was smaller along the stir zone and the thermo-mechanically affected zone. A square pin profile permitted greater frictional heat, which led to plasticization of the weldment and the pin. Based on comparisons with the other two counterparts, the friction stir welded joint made using the square pin tool had superior quality.

Published: January 2023

Environmental pollution and fossil fuel depletion are the major concerns in the present situation. Researchers have tried various biofuels for compression ignition (CI) engine in order to overcome these problems. Waste cooking oil (WCO) was found to be suitable alternate fuel for CI engine because of their huge availability, economically cheaper and renewable capability. However, WCO has poor fuel properties which led to inferior combustion in CI engine. Due to inferior combustion, engine performance was poor, engine exhaust emissions were higher. In this experimental work, different techniques were adopted to improve the performance of CI engine using WCO, as the base fuel. WCO was collected in bulk from a restaurant and used for the entire research work. A single cylinder, four stroke, direct injection, water cooled CI engine was used for this research work. In the first phase of work, experiments were conducted using diesel, WCO as fuel and kept as baseline data. WCO was converted into waste cooking oil biodiesel (WCOB) through transesterification process and conducted experiments using WCOB in the second phase of this work. In the third phase of the work, copper oxide nanofluids were prepared by wet chemical method in four mass concentrations, blended with WCOB and experiments were conducted. Finally, all the experimental outputs from various techniques were compared and analysed. It was observed that WCO produced lower brake thermal efficiency (BTE) and higher exhaust emissions than diesel. In the second phase, BTE was improved while using WCOB as compared to WCO. HC, CO emissions and smoke opacity were reduced. But nitric oxide (NOx) emission was found to be increased as compared to WCO. It was noted that BTE was improved further while using copper oxide nanofluids blended with WCOB. Emissions and smoke were drastically reduced as compared to WCOB and WCO.

For a successful ignition, the ignition should happen at the right time and place. If the ignition is not performed correctly, then substantial damage can occur both within and outside the engine surface. During ignition, the propellants should mix in a proper proportion. During the injection of propellant, the pressure and temperature are generally in subcritical condition. When they are injected inside the combustion chamber, they rapidly grow and transform into supercritical. The combustor shape is utilized to reduce the intention mixture rate and the computational domain encompasses the portion of this design. This is studied in this work by varying the inlet angles of the fuel. By changing the inlet angles (2.5, 5 and 7.5), the initial ignition time can be reduced. The simulations are done using ANSYS Fluent. The initial turbulence is reduced up to a certain angle and then, it starts decreasing. In the same way, the difference is observed in chamber pressure which rapidly increases, followed by a decrease. It can be concluded that 5 angle shows better performance in terms of pressure and velocity turbulence.

India has the world's second-largest population and the demand for transportation is increasing. However, our energy resources for car engines are limited. Every day, India consumed over 4.9 million barrels of crude oil. 85 percent of total oil consumption is imported from nations such as Iran, Saudi Arabia and Russia, among others. India is ranked third in the world. Despite our efforts to transition from internal combustion to electric power, India's electricity is heavily reliant on coal, which accounts for 55 percent of total production. As a result of this circumstance, jatropha biodiesel is being sought as a diesel engine alternative fuel. According to the Indian government, the country will spend about Rs 8 lakh crores on diesel and petrol imports in 2021, with this figure expected to rise to Rs 25 lakh crores in the next five years. The features of jatropha biodiesel with various percentages of blending with diesel fuel, such as B0, B5, B10, B15, B20, B30, B40, B50 and B100 are investigated in this work.

Published: January 2023

The objective of this paper is to provide a solution to a serious issue in today’s world of transportation through railways. The practice to examine the flaws which leads to serious effects in rail track is rail inspection. Among the world countries, Indian railways are the fourth-longest, but when it comes to reliability and safety it lags to provide world standard. As a result, if the track is damaged, it leads to severe loss of valuable human lives and property. This derailment in tracks is caused due to cracks in the rails. Therefore, an early crack detection and protection system is required to save the lives. This paper proposes a customized design of an inductive transducer and crack detection system on railroad tracks to avoid the train accidents. Existing method uses the manpower to identify the cracks and this involves human errors. So, the drawbacks in the existing method can be reduced by the automatic system. Customized inductive sensor is designed and developed using ANSYS. A scaled down model of a cart is fabricated and the inductive sensor is assembled at beneath surface of the cart. The track is acting as a part of the magnetic core for the inductive sensor and voltage is induced in the sensor. The sensor voltage is calibrated to distinguish the magnitude of voltage from the normal to crack.

The study was focused on investigating the spray and droplet characteristics of spiral and flat-fan nozzles computationally. The Spiral nozzle and the flat-fan nozzle are generally used in fire suppression application. The computational analysis had been carried out in ANSYS. The nozzle parameters like spray pattern, spray flow rate, impact, weber number were examined at different pressures say 1 bar to 3 bar. During this study the volume fraction of air and water were maintained equally. The spray pattern of spiral nozzle is not uniform and the droplets produced from the spray are coarse. The flat-fan nozzle produces a solid-cone pattern spray with oval impact area with a width of approximately ½ of its length. The flat-fan nozzle has higher spray flow rates and higher sprays impact than the spiral nozzles. The spiral nozzle acquires the maximum spray angle and the minimum droplet size and hence it is considered as highly efficient spray nozzle.

Our objective was to determine the needs of the U.S. food industry to control COVID-19 in the work environment and what mitigation strategies are being implemented. A Web-based needs assessment survey was distributed in early 2021, targeting professionals in management positions at food industry facilities and operations. Statistical analyses were conducted on the self-reported adoption of mitigation strategies against COVID-19 in the participants’ facilities and operations and the perceived needs of the industry regarding COVID-19. A total of 79 usable responses were received (those with data on the participant’s industry sector), including 38 (48%) from the dairy, 17 (22%) from the fresh produce, and 24 (30%) from a mixture of other food industry sectors. Two usable responses were from the beef and pork sector, but none were from the poultry sector. Analyses revealed widespread implementation of mitigation strategies in the participants’ facilities and operations. Participants perceived that collaboration between the food industry and government agencies, contingency plans and appropriate training, and new technologies are needed to control COVID-19 in the food industry. Subject to limitations associated with low participation, these findings will aid efforts in the represented U.S. food industry sectors to protect workers’ health in the event of the emergence of a new SARS-CoV-2 variant or similar future disaster.

Published: January 2023

With the voluntary adoption of good agricultural practices and the regulatory requirements of the Food Safety Modernization Act, produce growers have a continued need for educational programming. To understand these needs, the administration of produce safety needs assessments has increased. A summary of all available needs assessment research is needed to inform educational programming that addresses the complexity and range of produce safety requirements based on farm size and market access. This semisystematic review of 34 needs assessments from 2005 to 2020 summarized known produce safety needs and how those were influenced by a variety of factors among small- and medium-sized producers in the United States. Although growers face the needs of training, knowledge, time, capital, and mindset, the factors of farm size, region, market, and farm type influence how growers prioritize and are impacted by these needs. Therefore, educational programming cannot take a one-size-fits-all approach. It is essential to tailor education to the specific needs of producers while considering the various ways in which those needs can differ among specific groups of stakeholders because of influencing factors.

У статті розкрито основні аспекти здійснення соціальної роботи, до якої буде залучений у своїй майбутній фаховій діяльності магістр дошкільної освіти. Автором визначено сутність таких понять: «патронаж», «патронат», «соціально-педагогічний патронат», «соціальна робота», «соціально-педагогічна служба», «спілкування», «слухання», «спілкування», «не-рефлексивне слухання», «рефлексивне слухання», «перефразування», «з’ясування». Відзначено, що в усіх розвинених країнах світу соціальна робота є своєрідним проявом рівня цивілізованості суспільства. Розкрито сутність проведення соціальної роботи за кордоном. Виокремлено основні завдання соціальної підтримки родин, що опинились у скрутних умовах і потребують соціальної опіки; подано перелік таких сімей, визначено, яка саме допомога їм надається в країнах Євросоюзу, США, Великобританії та Австралії. Виявлено прямий зв’язок між якістю проведення соціальної роботи та стратегією допомоги, яку приймає уряд певної держави по відношенню до різних типів сімей, що потребують опіки. Розкрито сутність окремих наукових підходів до проведення соціальної роботи в країнах близького та дальнього зарубіжжя. Пояснено основні причини затребуваності соціально-педагогічного патронату як альтернативної форми здобуття дошкільної освіти.

Перелічено основні напрямки проведення соціальної роботи в Україні. Доведено важливість дотримання принципів діяльності педагога в межах здійснення соціально-педагогічного патронату. Визначено, що здійснення соціально-педагогічного патронату, побудова взаємодії з дитиною та її батьками на принципах партнерської взаємодії, можливе лише за умови оволодіння майбутніми магістрами дошкільної освіти спеціальними вміннями та навичками, що дозволяють проводити діагностику сімей, які опинились у складних життєвих обставинах. Встановлено зв’язок між функціями, що їх повинен виконувати педагог, який включений до системи соціально-педагогічного патронату, та знаннями, вміннями і навичкам, якими він має оволодіти після завершення педагогічного закладу вищої освіти. Названо провідну мету здійснення соціальної роботи. Підкреслено важливість проведення діагностування сімей, які потребують соціальної опіки від держави. Розкрито значення провідного методу реалізації завдань соціально-педагогічного патронату – консультування. Перелічено особисті якості, що мають бути притаманні педагогу, який здійснює соціальну роботу. Запропоновано приблизну функціональну модель педагога, який може виконувати роботу в межах соціально-педагогічного патронату. У результаті дослідження було зроблено висновок про необхідність навчання магістрів дошкільної освіти створенню власного іміджу як основи ефективного виконання завдань соціальної роботи.
