摘要
颗粒主要借冲击碰撞作用被粉碎。本文应用动量定理、体积功耗学说及断裂力学理论推导出冲击碰撞速度与碰撞前颗粒内裂纹长度之间的关系,得到了颗粒破碎的最小速度,此结论与先前的研究结论一致。
Granule is cracked by impact. In this paper, the theory of momentum ,the theory of volume work loss and the theory of fracture mechenics are applied to deduce the relation formula between the impact velocity and the inner crack length before impact and to obtain the minimum crack velocity of granule. The conclusion is the same as the former research.
