Finite Eleemnt Frontal Crash Analysis Of Nev Vehicle’s Platform With Upper And Sub Frame Body

Abstract

One way to improve a vehicle's performance is to reduce its weight. This is only one way to maximize performance. Given the recent advancements in the field of composites, it is clear that these materials may be the most effective substitutes for heavier materials, but we must take care to preserve their strength. Because composite materials are lighter, stronger, and more recyclable than other materials, research and development on them has profited immensely. In this thesis, ANSYS workbench is used to conduct a comparative computer-aided engineering study for the crash worthiness of an automobile body structure that was developed using CATIA V5 software. The primary benefit of CAE is that, without actually constructing the original component, the automobile body structure can be evaluated in a variety of environments to ensure optimal performance and durability. Three distinct materials, including AA7075 T651, stainless steel, and carbon fiber composite, are used to construct the car's body structure, and its crashworthiness is evaluated. Through the use of optimization techniques, the bulk of the automobile body is reduced while maintaining structural rigidity and durability. The ANSYS workbench software is used to do the CAE analysis and weight reductions. To determine the best materials that minimize weight while retaining stiffness and durability, the findings will be compared and discussed with the corresponding stress and total deformation value.
