Abstract

With the mass production of cars and utilities, the incidence of car accidents is increasing, while the case of car accidents in a variety collision probability is highest. The theory of the explicit nonlinear finite element which is adopted in the crash simulation is expounded. According to the European regulation of ECE-R42, a finite element model of low-speed crash between car bumper system and pendulum are established. The stress and strain contours, the displacement of node which on the deformation parts of bumper beam, the amount of compression of crash box and the process of energy conversion, etc. In the simulation results are objectively and deeply analyzed through HyperView. Finally, the paper discusses the influence factors on collision characteristics, such as the section shape, thickness and material properties of bumper beam.
