摘要: 为降低行人在碰撞过程中的损伤程度,探讨碰撞中的多元因素对人体损伤程度的影响机制,搭建人车碰撞仿真平台,建立人车碰撞数学模型,利用真实事故案例现场数据,验证模型的有效性。借助该仿真平台,计算在不同多元关联因素影响后的行人的运动学响应及损伤程度。研究表明:二次碰撞中行人头部损伤是导致行人死亡的主要原因;保险杠高度越接近胫骨高度,胫骨加速度和膝关节的弯曲角度越大;减小保险杠倾角能降低行人腿部损伤风险。

Abstract: In order to reduce damage to the pedestrians in the pedestrian-car collision process and discuss the mechanism by which the multiple factors influence pedestrian injury, a platform of vehicle crash simulation was established and a model was built. The effectiveness of the model was checked through real accident case information. The simulation platform was used to calculate pedestrian kinematics response and damage degree after collision under multivariate factor conditions. The research shows that injury caused by collision between the pedestrian head and the earth is the main cause of the pedestrian death, that there is a positive correlations between the shin acceleration or the bending angle of knee joint and closeness of height of the bumper to height of the shin, and that reducing the bumper incline angle can decrease the risk of pedestrian leg injuries.

Key words: pedestrian-car collision, kinematics response, pedestrian injury, multiple factors, simulation parameters design
