英文摘要：

It analyzed and designed a new wind turbine gearbox fault simulation test-bed,which could limberly simulate vibration circumstances of different structure of wind turbines.It is convenient to simulate different kinds of faults.Simultaneously,both the variable-frequency motor and the flywheel were adopted to simulate the torque input and the angular velocity input of an actual wind turbine,which was closer to an actual condition.Configured data acquisition and analysis system,the vibration circumstances of wind turbine gearboxes could be monitored and analyzed.According to the method of orthogonal design and simulating gear faults and bearing faults,the faults could be studied about wind turbine gearboxes.
