摘要/Abstract

摘要： 为研究摩托车骑车人与汽车碰撞后的动力学响应规律,基于国家车辆事故深度调查体系(NAIS)中的一个真实案例,利用PC-Crash软件建立摩托车与汽车前部成90°的碰撞模型,在此基础上,开展仿真模拟试验,研究骑车人坐姿和车速对摩托车骑车人头部损伤的影响。结果表明:轿车车速一定时,骑车人头部损伤指标(HIC)值随骑车人坐姿|θ|增大而增大;骑车人头部与轿车开始碰撞的时刻随骑车人坐姿|θ|增大而来得早。摩托车车速一定时,骑车人HIC值随骑车人坐姿|θ|增加而增加;骑车人头部与轿车开始碰撞的时刻随骑车人坐姿|θ|增加而来得早。

Abstract: In order to study the regulation of dynamics response for the motorcycle's rider and the car after the collision, based on a real case in the National Vehicle Accident Investigation System (NAIS), a 90°motorcycle and the car front collision model was built by means of the PC-Crash software. On this basis, simulation tests were carried out to study the impact of rider sitting posture and the speed of the car on rider's head injury. The results show that when the speed of the car is constant, the HIC value of the rider increases with the increase of the rider's sitting angle, that the point of time at which the collision occurs between the rider's head and the car comes earlier as the rider's sitting angle increases, that when the motorcycle speed is constant, this is a positive correlation between the HIC value of the rider increases and the rider's sitting angle, and that the point of time at which the collision occurs between the rider's head and the car's contact collision moment comes earlier as the rider's sitting angle increases.

Key words: rider, head injury criterion(HIC), rider's sitting angle, accident reconstruction, PC-Crash
