DESIGN AND DYNAMIC ANALYSIS OF ROLL CAGE FOR THE OFF-ROAD VEHICLE

A roll cage is a skeleton of an Off-Road Vehicle or the All-Terrain Vehicle. The roll cage not only forms the structural base but also a 3-D shell surrounding the driver which protects the driver in case of roll over incidents and all other impact conditions. The roll cage forms the main frame of the vehicle which contains other components like Engine assembly, Steering mechanism, Transmission assembly and the Driver. The roll cage also adds to the aesthetics of a vehicle. This paper deals with the Design, Development and Dynamic Analysis of Roll Cage for the off-Road vehicle. The roll cage model is designed with the help of SolidWorks software and Hyper Mesh is the software used for the Dynamic analysis. In the Dynamic analysis the different crash tests like front impact, side impact and head-on collision are carried out with the help of Hyper Mesh software for determining the optimum Factor of safety. By doing this analysis we can ensure the better strength as well as performance of the vehicle in various dynamic conditions.
