Abstract: The car's chassis is also called a structure that locates and mounts all the vehicle's components. It also creates a secure environment for the occupants. The chassis will provide torsional and flexural rigidity to the vehicle that makes the chassis one of the most crucial elements of the vehicle. Therefore, the front impact, rear impact, side impact, front torsional, rear torsional, vertical bending, lateral bending analyses were performed. The contribution of chassis is not limited to supporting the vehicle’s component, but it extends to providing better performance and aesthetics. Therefore, the design of the car chassis must be done accordingly. The current paper deals with the study of the design and analysis of the race car. The deformation, stress, and Factor of safety were considered as the evaluation parameters which were obtained by Finite Element Analysis (FEA) in Ansys software. To design the chassis, the SolidWorks software was utilized. Keywords: Car Chassis, Design, FEA, Material Comparison.

Abstract For the application of an automated, driverless race car, we aim to assure high map and localization quality for successful driving on previously unknown, narrow race tracks. To achieve this goal, it is essential to choose an algorithm that fulfills the requirements in terms of accuracy, computational resources and run time. We propose both a filter-based and a smoothing-based Simultaneous Localization and Mapping (SLAM) algorithm and evaluate them using real-world data collected by a Formula Student Driverless race car. The accuracy is measured by comparing the SLAM-generated map to a ground truth map which was acquired using high-precision Differential GPS (DGPS) measurements. The results of the evaluation show that both algorithms meet required time constraints thanks to a parallelized architecture, with GraphSLAM draining the computational resources much faster than Extended Kalman Filter (EKF) SLAM. However, the analysis of the maps generated by the algorithms shows that GraphSLAM outperforms EKF SLAM in terms of accuracy.

This paper examines the specifications of lithium battery cells, which are considered one of the most vital sources for electrical energy storage units. The specifications have been covered to associate battery performance with its usage for electrically powered motor vehicles. With the motivation of rapid deployment of electric vehicles (EVs) around the world, the key contribution of this study is to provide a comparative investigation of well-known commercially available Li-ion battery cells used as a pack for electric race car. Five lithium cells from different manufacturers were analyzed for start voltage, end voltage, current, and the use of active cooling under different test conditions. Thermal imaging was used to provide more comprehensive analysis of tested battery packs. The outcomes of this experimental investigation are described in the sections below in the order in which the analyses were conducted. The key findings of this study are presented in the conclusion section.

Yaw Moment

Direct Yaw Moment Control (DYC) is an effective way to alter the behaviour of electric cars with independent drives. Controlling the torque applied to each wheel can improve the handling performance of a vehicle making it safer and faster on a race track. The state-of-the-art literature covers the comparison of various controllers (PID, LPV, LQR, SMC, etc.) using ISO manoeuvres. However, a more advanced comparison of the important characteristics of the controllers’ performance is lacking, such as the robustness of the controllers under changes in the vehicle model, steering behaviour, use of the friction circle, and, ultimately, lap time on a track. In this study, we have compared the controllers according to some of the aforementioned parameters on a modelled race car. Interestingly, best lap times are not provided by perfect neutral or close-to-neutral behaviour of the vehicle, but rather by allowing certain deviations from the target yaw rate. In addition, a modified Proportional Integral Derivative (PID) controller showed that its performance is comparable to other more complex control techniques such as Model Predictive Control (MPC).

Design Competition

Formula SAE (FSAE) is a design competition organized each year by the Society of Automotive Engineers (SAE). The objective of the competition is to bring the best and brightest future engineers from each participating school to present a small scale race car. Although this sounds like a relatively simple concept, the actual execution is rather challenging and rewarding for the team. For almost three years Tennessee Tech University (TTU) has had a FSAE team. The first year was a planning year, so Tennessee Tech University has participated in the competition for the last two years. Both years have been extreme learning experiences since TTU was not prepared for the level of competition brought by participating schools. However TTU FSAE team is beginning to implement modern design tools such as FEA, Virtual Manufacturing, and Rapid Prototyping to help streamline the design efforts so that one day Golden Eagle FSAE will be one of the top competing teams. In this publication, authors will report on one Golden Eagle FSAE component (the rear upright) development stages and its accomplishments.
