摘要
为了解决直升机的振动问题,人们一直在研究各种减振技术。如何通过降低旋翼的激振力实现减振,是国内外这方面研究的一大课题。本文即对为降低旋翼激振力的减振优化设计分析的途径及其指针、桨叶设计分析模型、优化设计方法及灵敏度分析技术,以及减振研究的最新发展方向和需进一步研究的问题等方面进行分析和讨论。
As to helicopter vibration, many efforts have been made to reduce the vibration level. To design a rotor with lower vibratory loads is still a challenge to dynamics optimization. The survey gives an introduction to rotor vibration index, analysis model, optimization method and sensitivity calculation in various studies, and discusses the latest development and directions for further research in this area.
