摘要

为了研究间隙铰链对舵面传动机构动态特性的影响规律，基于一种改进的变刚度法向碰撞力模型，计入杆件弹性因素，分别进行了不同间隙值（

=0、

及

=1.6

）、不同摩擦因数（0.06、0.08及0.1）工况下舵机角速度、角加速度的数值模拟分析。结果表明，因间隙影响，舵机动态输出角速度、角加速度均呈现明显的振荡现象，且角加速度较角速度振荡幅值更大；同时，在驱动载荷发生变化时，角速度、角加速度均存在较大的波动，但无间隙情况下的波动程度较有间隙情况下更大；此外，间隙铰链处摩擦因数越大，角速度和角加速度振荡幅值越大，并伴随高频振荡和延迟现象。

Abstract

In order to study the dynamic characteristics of flap transmission mechanism with clearance joints

based on an improved nonlinear normal impact force model with variable stiffness

and the elastic factor of connecting rod

the angular velocity and angular acceleration of the steering gear are simulated and analyzed with the conditions of different clearance joints （

=0、

and

=1.6

）

and different friction parameters （0.06、0.08 and 0.1）. The dynamic output angular velocity and angular acceleration of the flap transmission exhibit obvious oscillation

and the amplitude of the angular acceleration is larger than that of the angular velocity oscillation; at the same time

when the driving load changes

the angular velocity and angular acceleration fluctuate greatly

but the fluctuation degree in the case of

=0 is greater than that with clearance; in addition

the higher the friction coefficient at the clearance joint is

the greater the amplitude of angular velocity and angular acceleration oscillation are

accompanied by high-frequency oscillation and delay phenomenon.
