Computer aided parametric design software are generally used for modelling of the vehicle components, to define all the coordinate values and geometrical details and then this CAD data is generally transferred to an FEM software for pre-processing and solution followed by generation and interpretation of results related to energies, acceleration and displacements with different loads & boundary conditions possible in various accidental situations. This major accomplishment is possible due to advent of advanced FE software system and computers offered within the last few years. Simulating the crashworthiness of the vehicle is a significant step to design automobiles of present age and automotive industry has probably the widest application of such simulation. Nowadays software such as LSDYNA, RADIOSS, ABASUS and others have very wide practical aspects to perform crash simulations. In the present work, Finite element modelling practices used for crash analysis are studied and after effects of the different parameters on the vehicle have been reviewed. The aim of this work is to study the effects of such crash parameters on the dynamic response of automobile component through finite element approach path. This paper presents an investigations of development done in the crash simulation of automobile components and the related process parameters through finite element approach.
