Abstract

This paper presented a design method of the flexible blade and its dynamic response under random wind. The flexible blade was discretized into multiple rigid bodies, and the multi-body system was established according to the theory of aerodynamics and the structural design of the blade. The nonlinear aeroelastic coupling equations of a constrained flexible blade are derived by the dynamics of multi-body system theory and the blade aerodynamics model, and the simulation program was developed. The examples analyzed time-domain responses of the blade under stable and turbulent wind speed, and the results were compared under these two kinds of wind speed.
