Based on the structural characteristics of the key parts of the planetary mechanism in the cutting section of coal mining machine,a simulation analysis method is introduced to realise the fatigue life analysis of the key parts of the planetary mechanism.This method needs to construct a rigid-flexible coupling model of the key parts of the planetary mechanism in the cutting section of coal mining machine,and then carry out the dynamic analysis and fatigue life analysis of the key parts of the planetary mechanism.After applying the simulation analysis method to engineering practice,it is confirmed that the simulation analysis method has high fatigue life analysis accuracy.
