基于共旋法的长柔叶片非线性气弹响应分析
Nonlinear aeroelastic response analysis of long flexible blades based on co-rotational formulation
摘要
Abstract
Aiming at the problem of unsteady and nonlinear aeroelastic response of flexible blades,an aeroelastic response analysis method for large-size wind turbine blades was constructed based on the co-rotation coordinate method and blade element momentum theory,coupled with the improved Leishman-Beddoes dynamic stall model.IEA 15 MW wind turbine was used as the model to calculate the aeroelastic response of blades under both steady-state and turbulent wind conditions,and the results were compared with FAST.The results show that the calculation accuracy of the co-rotational method is higher,and the numerical difference of the flapwise tip deflection is only 0.92%.It is of great agreement in the average value of load,and the maximum difference is 3.39%in the edgewise root moment.Compared with the FAST method,the co-rotational method has better convergence and stability.It can capture the convergent solution at a larger scale,has higher calculation efficiency,thus it is more suitable for complex nonlinear iterative solution processes.关键词
