阻尼环对齿轮系统轴向振动的减振特性研究

Axial vibration reduction characteristics of a gear system with a damping ring

分析了齿轮系统的振动机理与阻尼环减振原理。建立了齿轮—阻尼环系统的轴向振动的动力学方程组,采用谐波平衡法求解动力学方程,得到了近似解析解,并与数值解进行了比较。在此基础上,采用一组典型参数,讨论了系统的幅频特性,并探讨了齿轮—阻尼环系统减振效果与阻尼环参数的关系。

The vibration mechanism of a gear system was analyzed, and the anti-vibration principle as regards a damping ring device was elaborated. The axial vibration equations of a gear-damping ring system were established. The harmonic balance method was employed to obtain an approximate analytical solution which was used to compare with the numerical solution. On this basis, by using a set of typical data, the amplitude-frequency characteristic was discussed. The relationships between vibration reduction characteristics and the parameters of system were also discussed.
