| 摘 要： | 为提高自动驾驶车辆的安全性,提出用一种旋转速度曲线把座椅旋转至指定角度,研究此旋转速度下的乘员生物力学响应。首先,根据所建立的碰撞模型与假人试验数据进行对比验证;其次,改变座椅旋转方向和速度研究乘员旋转至指定位置乘员的生物力学响应。结果表明:在200 ms内采用等腰梯形旋转速度曲线旋转至±45°和±90°不会引起乘员额外的损伤风险。

| Abstract: | In order to enhance the safety of autonomous vehicles,a method is proposed to use a rotation speed curve to rotate the seat to a specified angle and the biomechanical response of the occupant under this rotation speed is studied.Firstly,the established collision model and dummy test data are compared and verified.Then,by changing the seat rotation direction and speed,the biomechanical responses of the occupant rotating to the specified position are studied.The results show that using isosceles trapezoidal rotation speed curve to rotate the seat to±45°and±90°within 200 ms will not cause additional risk of injury to the occupants. |
