To develop a reliable method for vehicle collision simulation, this paper carries out the computer simulation on rear-end collision of a passenger car based on the explicit dynamic finite-element theory. Firstly, a finite-element model of vehicle real-end collision was established by the virtual proving ground (VPG) technology and grid meshing. Next, a simulation of vehicle real-end collision was conducted according to the safety regulations of the United Nations Economic Commission for Europe (UNECE). The data on stress distribution, body deformation, body acceleraton and dummy injury were captured by the explicit dynamics analysis software LS-DYNA, and plotted into curves and cloud maps. The results show a stress concentration on the rear-ended vehicle, calling for structural improvement, and reveal the robustness of the VPG-based finite-element model in the prediction of vehicle crash safety. The research findings lay a solid basis for the evaluation of vehicle quality.
