说明：  对大型风力机柔性叶片的设计方法及其在随机风载荷作用下的动态响应与载荷特性进行了研究。根据风力 机叶片空气动力学和结构设计理论，将柔性叶片离散为多个刚体，形成一个多体系统。根据多体动力学的建模方法 和叶片气动模型，考虑两者的相互作用，建立了柔性叶片的非线性耦合动力学方程并开发了相应的仿真程序。算例 分析了叶片在随机风载荷作用下的气弹载荷与随机振动响应，并对稳定风速和紊流风速下的响应结果作了对比分析(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.)
