Qiu Yuan，Du Jie-feng，Chen Li-feng，Hua Mei-xia

［Abstract］For a large MW wind turbine spindle，the finite element analysis model of transmission chain is established based on finite element software. The effects of different contact types and different interference between the main shaft and the main bearing on the ultimate strength and fatigue damage of the main shaft are analyzed，and an optimal design of a main shaft is carried out according to the analysis results.

［Keywords］spindle；finite element method；interference；ultimate strength；fatigue damage
