摘要
直升机系统是一个流体、固体、刚体和控制相互耦合的非线性时变系统。其气弹响应问题的研究长期为国内外学者注视。本文对旋翼考虑不同的耦合层次，及诸因素的各项贡献，建立其耦合模型。应用Ｈａｍｉｌｔｏｎ变分原理建立旋翼系统运动方程。
The helicopter system is a fluid, solid and control highly coupled, nonlinear and time dependent dynamic system. Its aeroelastic response analysis has attracted aeroelastic researchers. In this paper, various coupled factors and their contributions are considered, the proper coupled model is established, and Hamiltons principle is used to derive the equation of motion of the rotary wing system.
