虚焦点位置对聚焦式隔振系统动态特性的影响研究

摘要

聚焦式主减隔振系统作为一种有效的直升机减/隔振手段已应用于多型直升机,取得了较好的减/隔振效果.国内对聚焦式主减隔振系统开展过一定的研究,但基本是将主减以及主减隔振系统简化为一维模型进行研究,缺少虚焦点三维空间位置对聚焦式主减隔振系统动力学特性以及对旋翼机身动载荷传递关系的影响的研究.以8自由度的三维参数化模型为基础,计算得到了虚焦点位置对聚焦式主减隔振系统动力学特性以及旋翼机身动载荷传递关系的影响曲线,为聚焦式主减隔振系统在型号中的应用提供一定的参考.%As an availability libration isolation system,the focal isolation system of helicopter has been widely used in multi type helicopters.In domestic research,the focal isolation system has been simplified as an one-dimensional mathematics model which was lack of theoretical studies on the influence of the location of focus on the dynamic behavior of the focal isolation system of helicopter.In order to provide some reference significance in the future development of focal isolation system of helicopter,a three-dimensional mathematics method which calculate the influence of the location of focus on the dynamic behavior of the focal isolation system of helicopter was shown in this paper.
