Design and Simulation of Chassis on ATV

ATV stands for All Terrain Vehicle which is specially designed for off-road driving. As these are used for very rough terrain, jumps, small scale forestry, border patrol, deserts and these are fun to drive so chassis has to be designed to withstand static and dynamic loads. Earlier ATV’s are built with ladder frame and back bone chassis which were heavier and lack protection. To overcome from this problem we are redesigning the chassis of the ATV in solid works, meshing and simulation of the chassis is done in ANSYS software. Finite Element Analysis (FEA) was utilized to determine the maximum stress and displacement of the frame when a particular load is applied onto it. Structure modifications need to be done if the chassis frame could not sustain the applied load. We began the task by conducting extensive research and hence the type of chassis we used is "TUBULAR SPACE FRAME" due to its advantages and withstanding capabilities. The results are provided in form of graphs by analyzing in ANSYS software. After the design process is completed, the fabrication of the frame is conducted by students of the engineering faculty. The fabricated frame will be used as the main part for a project of which a complete ATV will be developed.
