Taking 750kW wind turbine gearbox as study object

the dynamic simulation analysis of gearboxes by using virtual prototype technology is carried out.Based on three dimensional modeling software UG and according to the gearbox structure size and other design parameter

the solid model of wind turbine gearbox is created and after importing to ADAMS and adding constraints and load

virtual prototype model of the gearbox is established.The rigid dynamic analysis and flexible dynamic analysis of key components are carried out by using ADAMS

and the angular velocity and acceleration curves of the in-out shaft

gear meshing force and flexible body stress cloud are obtained.These result is coincided with the theoretical value through analysis and the accuracy of ADAMS simulation is verified.The simulation results show that the design level of wind turbine gearboxes can be improved by using the virtual prototype technology and lay a good foundation for further design.
