First Author | Under Review

Abstract

The automotive industry is undergoing a shift from internal combustion engines (ICE) to electric vehicles (EVs) as a result of increased awareness of climate and environmental issues. Governments around the world are implementing policies to reduce carbon emissions in the coming years. Developing electric powertrain for vehicles can be a challenge. The process of converting a vehicle to electric power requires extensive reverse engineering and careful selection of components such as the motor, controller, and batteries to ensure desired performance. This paper explores the previous research and feasibility of electric vehicle conversion, technical challenges, legality issues, and the conversion process in the automotive market of Bangladesh. Additionally, a methodology for converting an ICE vehicle into an electric vehicle by installing a conversion kit and other accessories is presented. The performance of the simulated model using Matlab is compared to real-world performance to justify the calculation approach, and the error in calculation is presented. The simulated model value was found to be accurate when compared to real-world results.

Optimizing aerodynamics in formula student race cars: A study on the development of multi-element active rear wings

Abstract

The use of active aerodynamic devices, such as rear wings, has become increasingly common in the design of modern race cars. In this study, we investigate the potential benefits of using multi-element active rear wings in Formula Student race cars. Through numerical simulations, we analyze the effect of different wing configurations on the aerodynamics of a Formula Student car. Our results show that the use of multi-element active rear wings can significantly improve the car's aerodynamic performance, compared to a traditional passive rear wing. By adjusting the angle and position of each element independently, the driver can optimize the wing for different racing conditions and track layouts. This can give the car a significant performance advantage over other cars that are not equipped with active rear wings. Overall, our study shows that the development of multi-element active rear wings is a promising avenue for improving the aerodynamic performance of Formula Student race cars. Further research is needed to optimize the design of these wings and to evaluate their performance in real-world racing conditions.

Abstract

Aerodynamics is a crucial factor for a racing car. Different aerodynamic devices are used to improve the aerodynamic performance of the race car. In an open-wheel race car, like formula one, front and rear wings have a huge effect on car performance. Modern technology is introducing an active aerodynamic system to vehicles. Nowadays, the drag reduction system is used in formula one cars which is a part of active aerodynamics. For a small race car, like formula student cars, wings need to be large to create expected downforce which also increases drag. So the effect of the drag reduction system is more important for a small race car. In this research different airfoil arrangements are designed and simulated in ANSYS for a drag reduction system for formula student race cars.

Abstract

The design of a suspension system has a significant role in vehicle dynamics. There is a different purpose of a vehicle which has different types of suspension systems. In the case of a race car, there are several factors that have to be considered. In this paper, a suspension system for a student formula race car is designed. The load calculation of a formula student race car is presented. Before load calculation, suspension geometry and upright or knuckle geometry are determined. Then the design of the rocker arm is determined from the value of the motion ratio. The spring is selected from the calculation of spring stiffness. The load during acceleration, cornering and braking are calculated. From that calculation, the maximum loads are accounted for by selecting the wishbone and pushrod pipe.

Abstract

Formula Student (or Formula SAE (F-SAE)) is a worldwide university competition, organized by the Society of Automotive Engineers (SAE), which encourages university teams to design, build, and compete with a Formula student race car. Design analysis of suspension especially for racecars is very crucial to achieve maximum performance and handling. Suspension design may vary depending on the road terrain and the vehicle purpose itself. The main objective of this project is to design and numerical analysis of a suspension system for a student formula car. We discussed the conditions, factors and FSAE rules that should be considered to design a student formula race car. According to the desired performance, some packaging parameters are selected and other suspensions and sprung parameters are calculated. Then according to the calculation, the suspension geometry is determined with an optimized result by numerical simulation in Lotus Suspension Analysis. Further, this process can be followed for designing suspension systems for any kind of vehicle.
