直升机旋翼结构优化设计研究综述

A survey of optimization methods to helicopter rotor structural design

本文综述了国内外关于直升机旋翼优化设计方法的进展情况。其重点在旋翼桨叶的减振优化设计。从中可以看出,现代结构优化设计方法已经成为当前直升机旋翼设计的重要技术之一,开展这一方向的研究和应用对提高旋翼设计水平、研制新型直升机是十分必要的。

The purpose of this paper is to survey the principal developments of apllications of the optimization methods to the helicopter rotor design problems, more specifically to the vibration reduction of rotor blads. It is the viewpoint of this paper that the methods of structural design optimization is ore of the most important technologies which have been used for designing the mordern helicop-ter rotors by now, and it is necessary to develop the structural optimization analyses of rotor blades in order to increase our technical competence.
