摘　　要：从刚体力学的角度，建立了一个汽车人──椅力学模型，引用凯恩方法导出了模型的数学计算通用公式。编制了一套模拟汽车碰撞过程中乘员运动响应的仿真软件。计算汽车正碰撞过程中人体的运动姿态，加速度，速度和位移响应，以及安全带的受力等特性。与试验结果比较，证明了软件的可行性和实用性。Based upon Ragid body Kinematics, the model of a two dimensional Occupant/seat system is described and the motion equation of it is deduced in kane method, A practical program of the occupant responses during vehicle crash is made. The computer simulation on vehicle-occupant motion is proved valid by comparing the simulated results with that by experiment. Analysis for the effect of safety belt is also presented in the paper.
