齿轮系统减振设计的支承结构灵敏度分析

Sensitivity Analysis of Support Structure in Design of Reducing Vibration of Gears

考虑轴和轴承的柔性以及由于轮齿啮合而产生的横向运动、扭转运动、轴向运动与旋转 (摆动 )运动间的动态耦合的影响 ,建立了齿轮系统的动力学模型 ,研究了齿轮系统特征值灵敏度分析方法 .

The dynamics model of gear system accounts for the shaft and bearing flexibility,the dynamic coupling among the transverse,torsional,axial and rotational (rocking) motions due to the gear mesh.The sensitivity analysis method of eigenvalues of gear system is researched.An example is given to illustrate the procedure.The results obtained are with guiding desiqn.This analysis method lays a foundation for carrying out the dynamic optimum design of gear system.
