摘要
本文以碰撞动力学和多体系统动力学中的R-W方法为理论依据,建立了汽车-乘员三维多体系统碰撞模型。在此基础上,开发了汽车碰撞计算机仿真软件SVC3D。仿真计算与试验结果的对比证明了模型的合理性及软件的正确性。应用该软件对汽车-乘员多体系统进行了仿真研究,得出了有工程指导意义的结论。
The three-dimensional model of vehicle-occupant multibody system is constructed according to impact dynamics and multi-body dynamics in this paper. The software named SVC3D (3D Simulation of Vehicle Crash) is developed on the basis of the model. The simulation results of SVC3D in comparison with those of test prove that the model is reasonable and the software is correct. Simulation research into passive safety of vehicle-occupant multibody system is carried out using the software and the conclusions with directive significance are drawn in the paper.
