| 摘 要： | 应用经典力学结合实验测试的方法,研究战士投弹训练中出现的肱骨骨折现象。研究表明,投弹骨折的发生与投弹姿势不正确有关,前臂运动的角加速度、角速度及肘部加速度过大,都可能造成损伤,特别是这些参数最大值同时出现(一般易发生在制动时段),是发生骨折最危险的时刻。

| Abstract: | This paper studied the phenomena of humeral fracture of Soldiers in grenade throwing training through using the method of classical mechanics combining with experimental testing.The result showed that the occurrence of humeral fracture was related with improper movement.When the angle acceleration and angle velocity of forearm was too high,it was the dangerous time for humeral fracture to happen. |
