Kinematics and Dynamics Simulation of Key Components of Wind Turbine

摘要

In the article, blade element momentum theory is used for calculated aerodynamic load of blade under the different wind velocities. 3D model of key functional components such as blade, tower, hub and nacelle are modeled in Solidworks, the MNF files of blade and tower are gained in finite element analysis software after flexible processed, and the rigid-flexible multi-body dynamic model of the wind turbine's key components is created in ADAMS. Through simulation of the model under constant rotate speed, kinematics and dynamics curves are got while the wind speed rise from 5m/s to 25m/s. This simulation can imitate vibration performance ideally. A feasible method is provided for the virtual prototype simulation of wind turbines.
