摘　　要：结合中国人体形特征和假人缩放方面的研究成果,提出了基于受害人体形特征的行人数字仿真假人快速定制方法。该方法通过交互式程序,只需输入受害人的身高和人体质量信息,就可以快速生成多刚体假人模型。文中还以一起真实的事故案例为例,研究了假人体形参数对仿真结果的影响,结果显示假人体形参数对事故再现结果的影响不容忽略,尤其是要注意假人的几何尺寸方面,而对于人体质量误差的要求则可适当放宽。Using the results of current research on Chinese anthropometrlc characteristics and aummy scaling technology, a method of rapid development of numerical dummy for pedestrian based on anthropometric features of victim is presented, in which only the height and weight of the victim are needed as inputs to generate multi-rigid- body dummy model by using an interactive program. The influence of the dummy anthropometrlc parameters on simulation results is also studied based on a real accident case. Results show that the effect of dummy anthropometric parameters on the results of accident reconstruction can not be neglected. The attention should be paid particularly on the geometrical dimensions of dummy while the requirements on the accuracy in dummy weight can reasonably be relaxed,
