基于人因工程的汽车碰撞过程中人员响应的仿真建模

通过人因工程分析,构造多刚体系统的人体模型,应用数理方法,建立高速公路汽车碰撞乘员动力学响应的数学模型,开发出仿真软件.应用该模型可以部分代替实车碰撞试验,进行汽车主、被动安全性能的计算机仿真研究以及乘员致伤机理研究.

Simulation modeling of personnel response in automotive collision based on human factors

By combining the Lagrange-Euler forms of multirigidbody system dynamics with classic collision theory, the dynamic equations of a collided tree topology system in Lagrange-Euler forms is derived. The occupant model of multibody system based on the analysis of human factors were applied to set up the physical and relative mathematical modeling of high ratio automotive crash on the right side of the express highway. The relevant computer software can be developed to replace some automotive collision tests to determine the occupants injured judgment, automotive active and passive safe performance, etc. It can also give the scientific bases for the effect of the disposition and material characteristics of automotive accessories to the occupants' safety.
