“…Finite-element analysis has been widely applied to the simulation of vehicle crash. Several research studies investigated how to develop a full vehicle model for crashworthiness analysis by FEA (Cheng et al [6]; Gursel and Nane [7]; Atahan [8]). Borovinsek et al [9] provided a brief overview of different types of vehicle collisions.…”

This paper investigates the behavior of impact loading on a Baja vehicle chassis with frontal and rear shock absorbers, using transient dynamic analysis under different assumptions of contact conditions. Using a Baja car, a transient dynamic impact is performed in ANSYS Workbench 14.0, where the maximum deformation, stress, and strains are calculated over duration of the particular impact. The mathematical model of the chassis is derived based on Kelvin model in order to design the best parameters of stiffness and damping coefficient in shock absorbers to minimize the deformation of the frame with the same impact. To study the effects of shock absorber under loading on a vehicle chassis, multiple finite element simulations are performed with different methodologies. Each methodology uses a different assumption on loading and boundary conditions, which leads to different results.
