摘要/Abstract

摘要： 为研究电动二轮车与SUV正面碰撞事故形态中,骑车人头部损伤指标(HIC)与躯干横摆角、前倾角及参与方碰撞速度的关系,基于MADYMO软件验证后的运动型多用途车(SUV)与电动二轮车多刚体模型设计仿真试验。结果表明:骑车人HIC值随躯干横摆角的增大逐渐减小;电动二轮车车速不超过15 km/h或SUV车速超过50 km/h时,骑车人HIC值随躯干前倾角的增大逐渐减小;电动二轮车车速超过15 km/h或SUV车速不超过50 km/h时,骑车人HIC值随躯干前倾角的增大先增大后减小;提前同时增大骑车人躯干横摆角和前倾角可降低骑车人头部损伤程度。

Abstract: In order to study impacts of torso yaw angle, torso anterior angle and participant's collision speed on cyclist's HIC in frontal collision accidents between electric bicycle and SUV, a simulation experiment was designed based on multi-rigid body model of SUV and electric bicycle verified by MADYMO software. The results show that the HIC value will gradually decrease as cyclist's torso yaw angle increases, and also do so as torso anterior angle increases when electric bicycle's speed doesn't exceed 15 km/h or SUV exceeds 50 km/h. Otherwise, it will increase first and then decrease with the increase of the torso anterior angle when the former exceeds 15 km/h or the latter no more than 50 km/h. Cyclist's head injury can be reduced by increasing torso yaw angle and anterior angle simultaneously in advance.

Key words: electric bicycle, sport utility vehicle (SUV), cyclist, torso, yaw angle, anterior angle, head injury criterion(HIC)
