Crashworthiness simulation of front bumper model of MOROLIPI V2 during head-on collision

Abstract

It is necessary to conduct an impact test for bumper collision. The use of bumper as a protective components of a vehicle during collision. On this Paper, a crashworthiness simulation of front bumper model with correspond to the size of MOROLIPI V2 is conducted. The purpose of this study was to obtain simulation result used as a reference to predict mechanical behaviour of bumper due to collision. The Simulation result can be predicted deformation after collision, von misses stress criteria after collision with static dummy load. To simulate impact on bumper, ANSYS Explicit Dynamics is used. Simulations were run at three values of mobile robot speeds (5, 10 and 20 m/s). The simulation results also show contact force due to the collision, deformation, stress and internal energy of the bumper beam. It was known that the speed of the vehicle is the dominant parameter determine the results of the crashworthiness simulation.
