data exchange between Pro/E and ADAMS has been achieved depending on the virtual prototyping technology through the data exchange function and load data which were exerted on the blade has been simulated applying SPLINE function and the Virtual Prototyping was built.Simulation analysis of dynamic characteristics such as speed and acceleration and gear meshing force,bearing force, the output torque load data in the pitching process, in order toverify the accuracy and rationality of the mechanismandmaster the regularityin the process the pitch and provides a reference for the research of the turbine pitch mechanism, which provides a reference for the research of the turbine pitch structure, at the same time,provides a way for multi-bination in turbine research.
