Kinetic Analysis of Wind Turbine Blades

This paper using ANSYS software such as wind turbine blades and other key components of the kinetic analysis and research, the kinetic analysis method and finite element analysis software combine to validate the experimental data is reasonable. Specific contents are: wind turbine blade dynamics analysis. The wind turbine blades as slender cantilever, so you can use the ANSYS program flexible dynamic analysis modules. The module is used to calculate the alternating loads flexible body structural response, namely due to the coupling effect of making wind turbine blades load acceleration, deformation at any time are changing. Also changes with time of the blade root of force and torque, the forces and torques of the hub provides theoretical data for further analysis. In this paper, the key components that wind turbine blades for the kinetic analysis, the relevant conclusions. Wind generator system for future scientific design, blades and other key components of the failure prediction assessment provides theoretical support. Wind turbine blades rotate in the movement through the air to promote the flow of the wind energy into mechanical energy, electrical energy eventually [. Leaves the force in the system is particularly complex, by gravity, such as the formation aerodynamic pull, bend and other effects and coupling effects [. Leaves elongate resilient structure is characterized by large-scale, flexible. During operation, the fan blade damage resonance is an important reason, it is how to use the features to reduce structural failure of the fan so that the safe operation of wind power generation is one of key technologies [. Wind force generator is one of the most complex parts blades, due to its tangential short span long, flexible, and therefore prone to vibration, wind turbine blades are a variety of mechanical vibration occurs first site. Therefore, from the wind turbine operation and design considerations for wind turbine blades for stability margin analysis and linear stability analysis are important.
