Explicit Analysis of An Automobile Chassis when Collision

Generally, Vehicle crash is considered as nonlinear transient dynamics phenomenon as impact causing car to stop with time frequency. The purpose of explicit analysis is to see how the car will behave in a frontal or sideways collision. Crash worthiness simulation is one type of application of finite elemental analysis (FEA). It is very effective to conduct nonlinear finite element simulations. The chassis frame is backbone of a vehicle as the whole deck is bolted to the chassis. The principal of chassis is to carry the maximum load which is designed for its operating conditions. The frame must support the components and the body for operating conditions and also it must with dynamic and structural conditions without any deflections. In this project, the car frame model is simulated and analyzed using ANSYS software for impacts and collisions in the frame. The designed model is tested under different collision conditions and the resultant deformation and stresses are determined with respect to a time of 80 Milli sec for ramp loading using ANSYS software. Explicit analysis is done on car frame in different directions using ANSYS software.
