Abstract

Accurate evaluation of fall accidents is very important. We have done the experiment in JARI using human-type robot which simulates the human accidental injury. The precise data of acceleration has been taken from the robot. Using the acceleration data, the motion of the head center is derived. The speed and the position of the head center are determined under a realistic condition. The deformation of head surface is also calculated and was found that it is 1.0~1.2 mm in a natural falling. The solutions of a long interval of 324 ms are shown.

跌落冲击时头部变形的精确分析
对坠落事故的准确评估是非常重要的。利用模拟人体意外伤害的人形机器人在JARI中进行了实验。从机器人上获得了精确的加速度数据。利用加速度数据,导出了头部中心的运动。在现实条件下确定了头部中心的速度和位置。计算了头表面的变形,发现在自然下落时,头表面的变形为1.0~1.2 mm。给出了长间隔324 ms的解。
