摘要
运用应力波理论和动量守恒等原理,根据相撞物体的材料性能、形状、截面积、长度和撞击前的速度,编制了程序,计算出了任意形状、多个构件正撞击后的速度。其计算速度与实测速度误差小于5%。
In the paper, the velocities of arbitrarily shaped components after positive impacts with each other are calculated using a computer program reflecting the materials' properties, shape, cross-sectional area, length and velocities before collision, based on the theory of stress wave and the principle of conservation of momentum. Errors between the computed velocity and that from practical tests are found to be less than 5%.
