汽车-行人碰撞多体动力学仿真与抛距模型研究
Simulation of Car-Pedestrian Collision Multi-body Dynamics and Study of Throwing Distance Model
摘要
Abstract
Vehicle-pedestrian collision is a major type traffic accident in China. Because of its high fatality rate and closely related with people's travelling, people pay close attention to this type of accident. However, it is difficult to handle such kind of accident with common use "accident analyzing method". Based on multi-body dynamic theory, the paper built a numerical multi-rigid-body pedestrian model as a platform for PC-CRASH to simulate the collision between vehicle and pedestrian. Through setting rigid-body characters of different parts of the pedestrian (appearance , mass, rigid, friction factor) , the characters of pedestrian can be defined. The model was validated by comparing with a real car collision experiment abroad. The speed throwing distance was obtained through the regression analysis of simulation results. It provides numerical reference for such vehicle-pedestrian traffic accident. [Ch,5 fig. 3 tab. 13 ref. ]关键词
