| 摘 要： | 直升机旋翼系统是直升机的核心部件,弹性轴承将桨叶与桨毂相连,提供桨叶的挥舞、摆振和变距自由度,刚度特性是其主要的力学性能.通过采用松紧螺套驱动半圆形夹具转动来测试弹性轴承压缩、扭转和弯曲刚度特性,结果表明该试验方法新颖独特,具有一定的通用性,能准确判定弹性轴承是否合格,可为不同机型的弹性轴承提供装机前试验的方法.

| Abstract: | Rotor system is the core component of the helicopter,flexible blade with the spherical thrust bearing connected to provide the wielding,shimmy and pitch degrees of freedom,the stiffness characteristics is one of the main mechanical properties.Test the spherical thrust bearing compression,torsion and bending stiffness characteristics by twisting the screw to drive the semi-circular fixture.These results indicated that the test method is distinctive and general.It can accurately determine whether the spherical thrust bearing is qualified and provide a test before installing for different type of spherical thrust bearings. |
