煤矿机械设计中的冲击力的计算１前言我们知道两个物体相碰撞就会产生冲击，由于冲击作用的存在，在设计任何机械设备时，随机力系数都要提高一定的百分比，许多机械设备在实际工作中尽管并不存在着实际的碰撞现象，但为了适应可能出现的瞬发载荷或由于机构自身质量不平衡... Calculation of Impact Force in Coal Mine Machinery Design 1 Introduction We know that impact between two objects will produce an impact. Due to the impact action, the random force coefficient must be increased by a certain percentage when designing any mechanical equipment. In practice, although there is no real collision phenomenon, but in order to adapt to the instantaneous load that may appear or because of the imbalance of the quality of the mechanism itself ...
