Abstract The energy is less and less on the earth, The development of new energy, wind energy as a new energy has been paid more and more attention .However, wind power generator when at work due to vibration and other reasons, often can not work normally. Research and development of damping support is particularly important..

The gear box of wind generator hydraulic elastic support as the object of study, analysis of wind turbine gearbox movement of hydraulic elastic support, the structure design of gear box hydraulic elastic support, through the three-dimensional modeling and finite element analysis software to calculate damping demand to ensure the wind turbine gearbox hydraulic elastic support. The main research contents include the design of hydraulic elastic support structure for wind turbine gearbox, for parts for 3D modeling and understanding of hydraulic elastic supporting principle, installation process,  master the structure, part of the product and the role of mutual cooperation relationship. Study of finite element analysis software ABAQUS, the mechanical analysis of the stress analysis, elastic support, understanding the working environment and the performance of the hydraulic elastic support, pretightening force calculation of stud, and the leakproof plug seal selection.

Key words: The wind generator;Gear box; Hydraulic elastic support;   ABAQUS finite element analysis;
