摘要
The numerical analysis on a shaft with rub-impact condition is done by using the finite difference method. The bending modes and the moment yaring along the shaft are described,to reveal the in crease pattern of sectional stress of the shaft. The result obtained in this paper can be used in explaining the phenomena of many breaking sections appeared in destructive failures of actual rotating machinery.
应用有限差分法，计算出碰摩转子的挠曲振型和截面弯矩分布的变化情况，从而直观地揭示了碰摩过程中转子截面应力的增长规律，对一些旋转机械重大事故中转轴出现多个断口的成因做了初步解释．
