摘要
本文提出了应用直升机动力学设计技术对风轮叶片和塔架分别建模、应用模态综合技术分析风轮/塔架耦合系统动力学特性的方法。分析了孤立风轮叶片、塔架系统的振动特性与风轮/塔架耦合系统振动特性之间的变化,指出了在风轮叶片和塔架系统振动特性设计中应考虑的一些因素。
In this paper a method for dynamic behavior analysis of coupled wind-rotor and tower-frame is given out in which the techniques of modeling wind-rotor blade and tower structure respectively and mode synthesis are employed from helicopter dynamic design.The differences between dynamic characteristics of isolated blade、tower and coupled wind-rotor/tower are analyzed.Some factors needed comsidering for wind-rotor blade and tower-frame dynamic design are pointed out.
