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.

Formula Student Racing competitions are held at various Formula SAE circuits globally. Chassis serves as an important component in the race car design. Thus a solicitous analysis is expected out of the formula car. It is also noted that the weight of the car is inversely proportional to the performance of the car hence need for optimization. A high speed protection system plays a major role in the race car design such as front impact, rear impact, side impact and roll over analysis. Also, there exists a problem of the torsional rigidity as far the dynamics is considered. This paper aims at the design aspects and the analysis insights of the race car. The car is modelled according to the 95th percentile male that can fit inside the cockpit of the chassis. As the car travel at the high speed, the protection has been designed to the car in such a way that stresses are minimum and the performance is maximum. Finite element methods are used for the analysis and the design of experiments is created for the optimization of the chassis. To avoid any possibilities of failure of the structure and thus to provide enough supporting member to make the region stronger in term of deformation . Finite element analysis enables to predict the region that tends to fail due to loading, the distribution of stress and strain on the chassis, both component as well as the material costing. The main objective is to study the effect of the validations of the FEM result are given using the different profiles like RECTANGLE, CIRCULAR, AND I SHAPE convergence methods for car body and the equipment.

This study investigates different chassis designs through a simulation-based design approach. The inherent aluminum ductility and softness could make chassis a daunting modification if not analyzed properly. Structural finite element analysis is comprehensively performed on a vehicle chassis for static loading cases up to 1G in equivalent acceleration. The analysis of the vehicle chassis of both A36 steel and 6061 aluminum for the scenarios of bump, front impact, side impact and a rollover. The von Mises stresses and displacement results showed that the steel chassis possessed higher safety factor in all load cases. The safety factors for an aluminum clone of the steel chassis in some load cases are below 1.0, hence indicating that the failure criterion has been triggered and failure would occur under the 1G load. The original aluminum chassis deformation is far more severe than steel reaching as high as 9.88 mm for the bump loading. A modified aluminum chassis is proposed, by optimizing the wall thickness of the rectangular bars. The slight increase in weight resulted in overcoming the deficiency of aluminum in load carrying capacity. An evaluation matrix procedure is implemented to analyze the trade offs between cost, weight and safety factor for the three chassis materials.

Design and analysis of Buggy roll cage commonly used as a recreational vehicle on off road terrains have been studied. These vehicles are usually modified from their existing design to provide performance and safety. In this research paper, an attempt has been made to design a roll cage for a buggy considering different members of the roll cage. In this context roll cage has been drawn on solid works CAD software and has been analyzed using finite analysis by applying the different boundary conditions. The roll cage has been designed considering the AISI 4130 steel and carbon fiber considering five cases such as front impact, side impact, rear impact, drop test and roll over test to ensure safety of the operator to survive the impact scenario. The main significance of this study is to analyze buggy role cage from safety point of view of operator. From these results it can be concluded that carbon fiber roll cage is also one of the promising alternatives for roll cage design and can be recommended from safety point of view.

The objective of this research is to design a spaceframe chassis for light weight automobiles possessing unladen weight of ≤ 550Kg to replace the conventional monocoque type chassis frame. The maximum stress and maximum deflection that the chassis can resist without fracturing are important criteria. In this thesis, the existing monocoque chassis was considered and analyzed under static loading, frontal impact, side impact, rear impact, front rollover and side rollover loading conditions by using Finite Element Analysis method. Then, taking the test results as a reference, a spaceframe chassis was designed for the same size vehicle. The critical evaluation standard points stated in the Federal Motor Vehicle Safety Standard (FMVSS), U.S.A standard, were used as guideline to see the performance of the existing and the new chassis frames. The test results show that a space frame chassis has better stress resisting capacity and reliability than the conventional monocoque chassis frame under all impacts.

In the present work, the numerical analysis of the structure of a prototype of a SAE BAJA type automobile chassis is developed. Within the proposal of the model, factors that become important when implementing it are considered, these factors are: driver safety, sufficient spaces for vehicle components, among other basic points. Likewise, the model is subjected to different tests established by the Society of Automotive Engineers (SAE), tests such as: Front impact, rear impact, side impact, overturn, landing tests for front jump and rear jump; the conditions to which these tests are subjected are extracted from articles (tests) and applied in the appropriate areas to have the most accurate and close to reality results. The analysis is carried out with different materials and profiles used for structural members, in this way the appropriate configuration of the profiles and materials is also obtained. Due to the satisfactory parameters obtained, a fairly efficient model is obtained, this has an impact on the necessary safety for the driver, basically, because the system has low deformations in the materials and withstands relatively high stresses.

According to the situation that the dual-friction drums on the new type towing machine lack stress analysis when designed, the safety is difficult to test and verify. The pull of wire rope in various positions was derived and calculated, so both compressive stress and tangent friction force generated by the pull of wire rope were calculated. The result made by ANSYS software demonstrates the safety of the left drum which suffers from larger loads, structure improvement measures are put forward for the drum.
