摘要

舵机系统是典型的机械传动系统，传动过程中的部件间隙对系统动力学特性有很大影响。本文针对多级齿轮和丝杠螺母组合的舵机系统，建立含有齿侧间隙和内部激励误差的平动-扭转运动动力学方程，利用谐波平衡法分析系统的固有频率及周期运动幅频响应，利用数值方法求解、分析传递误差、碰撞和分岔与混沌运动现象，并分析讨论了多间隙和单间隙对系统动力学特性的影响差别。本文分析可以为舵机系统结构参数和操作参数的优化设计、提高传动效率和平稳性提供参考。

Abstract

Steering Gear transmission plays an important role in various transmission systems. This paper investigated the dynamic behavior of a steering system with several backlashes. First, the equations of motion of a 3 degree-of-freedom dimensionless system were established. Then the modal analysis was used to analyze the natural frequencies and amplitude-frequency spectrum of the system with harmonic balance method. Secondly，the system was also numerically solved by Runge-Kutta method and bifurcation, chaos and other complex dynamic phenomena were presented. Finally, influences of gear backlashes on dynamics of the system were analyzed. The result of the paper indicates that both the operating conditions and the structural parameters of the steering gear system can be designed properly to avoid undesirable dynamic motion and realize better mechanical properties.
