蜂窝填充MW级风机叶片非线性动力学建模
Nonlinear dynamic modeling of honeycomb-filled MW-level wind turbine blades
摘要
Abstract
In response to the significant nonlinear effects caused by the large-scale development of wind turbine blades,dynamic modeling of the bending vibration of large wind turbine blades was established based on the geometrically exact beam theory.The blade was considered an Euler-Bernoulli beam,and the kinetic energy,elastic potential energy,gravitational potential energy,aerodynamic loads acting on the blade,and the work done by these loads were derived.The nonlinear dynamic equations were then formulated using Hamilton's principle.The natural frequencies obtained from theoretical calculations and the ABAQUS finite element model were compared to validate the correctness and scientific soundness of the derived theoretical model.By comparing the maximum deflection of wind turbine blade vibrations with and without honeycomb structure filling,it is demonstrated that honeycomb filling can effectively reduce blade vibration and enhance the operational capability of the wind turbine.关键词
