By adopting the elastic contacting finite element method

the contacting simulation of the increasing speed gear system for 1MW wind-power generation is carried out and the correlated problem in the meshing calculation is studied.Based on the software Pro/Engineer

the solid model of the increasing speed gear system for wind-power generation is built.By using the software ANSYS

the contact and bending stresses are obtained.According to the obtained results

the most dangerous disk position of the gear system for 1MW wind-power generation is found.It is significant to improve the load capacity and the performance of gear transmission of wind turbine.
