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。
Focusing main damping system as an effective means of helicopter reduction / vibration isolation has been applied to multi-helicopter, and achieved good reduction / isolation effect. In China, some researches have been done on the main vibration reduction system with focus, but the basic one is to reduce the main reduction and the main reduction vibration isolation system into one-dimensional model. The lack of the virtual three-dimensional spatial position to focus the main vibration reduction system The study of the characteristics and the influence on the dynamic load transfer of the rotor fuselage. Based on the three-dimensional parametric model of 8-DOF, the influence of the position of the virtual focus on the dynamic characteristics of the main vibration isolation system and the dynamic load transfer relationship of the rotor fuselage is calculated. The type of application provides some reference.
