Abstract

Multy-body simulation is applied to compute the motorcyclist’s kinematic in case of virtual motorcycle versus car accident. Results show that for over 50% of the simulations, the impact velocities of the whole body exceed 8 m/s when impacting the vehicle and 4 m/s at the time of road impact. The head impacts the vehicle most often with a speed exceeding 7.5 m/s in the fronto-lateral impact configuration, when thorax, abdomen and pelvis are the most exposed segments for the other impact configurations, with impact velocities beeing in the range of 10 to 15 m/s. Changes in BMI leads to minor influence on the impact velocities of the different body, especially for the first impact. As expected, body impact speed increases with the speed of the motorcycle, for both, the first and the second impacts. These results will contribute to an improvement in the evaluation and optimization of motorcyclist’s protection garnement.

摘要

在虚拟摩托车与车祸的情况下，多体仿真用于计算摩托车手的运动学。结果表明，超过 50% 的模拟中，整个车身碰撞车辆时的碰撞速度超过 8 m/s，道路碰撞时超过 4 m/s。在正面横向碰撞配置中，头部最常以超过 7.5 m/s 的速度碰撞车辆，而胸部、腹部和骨盆是其他碰撞配置中暴露最多的部分，碰撞速度在 10 到 10 到15 米/秒。BMI 的变化对不同身体的撞击速度影响较小，尤其是对于第一次撞击。正如预期的那样，对于第一次和第二次撞击，车身撞击速度随着摩托车的速度而增加。
