摘要
本文以质点动力学理论为基础,对磨内最外层的任一研磨体在任意时刻的受力情况进行了分析,建立了研磨体的受力平衡方程式,并依据牛顿力学定律,求取了研磨体在脱离点的初的速度、研磨体被抛出后的运动方程、研磨体作抛物线运动的时间以及磨内研磨体在落着点的速度向量和研磨体的碰撞力向量。
This paper based on the particle ddynamics,analyse the force problem of any stell ball Located on the outer tier inaide mill at arbitrarly time,establish the force equilibrium equation of thatsteel ball and additionally solues the speed uector and collided torel uector of the steel ball inside mill at the descended point.
