Strength and Mode Analysis of Testing Machine of 3MW Wind Turbine Bearing with Finite Element Method

Wind turbine always run in complex environment, as the key components of wind turbine, it is extremely important to test wind turbine bearings properties, so we need develop a testing machine to test their properties. The static strength and dynamic properties of testing machine key components of 3MW wind turbine bearing were analyzed with the finite element software ANSYS to obtain the strength and stiffness check as well as the optimizing design of testing machine key components of wind turbine bearing. The strength was checked and satisfied with the demand of material strength. The former five orders natural frequencies and corresponding modes were obtained, which provides scientific basis for future design．
