Abstract
In this study, the deformation and stress values of the chassis made for the Efficiency Challenge electric vehicle competition, one of the Teknofest competitions, were investigated using the finite element method under impact and static loads. The chassis was designed with the Solidworks program, taking into account the chassis design criteria of the efficiency challenge race. With the help of Ansys Workbench, the designed chassis was analyzed under static load depending on the front, side, rear impact and the mass on it. According to the analysis results, the chassis withstood static loads. However, in the crash tests, the maximum stress value was above the yield value. According to the maximum stress points on the chassis, the chassis was redesigned and the analyzes were repeated.
