面齿轮-行星齿轮耦合传动系统非线性动力学研究
Study on nonlinear dynamics of face gear-planetary gear coupling transmission system
摘要
Abstract
To study the influence of eccentricity error on the dynamics of helicopter gear transmission system,a face gear-planetary gear dynamic model with gear eccentricity error was developed,while nonlinear elements were also taken into account,including backlash,tooth friction,and time-varying meshing stiffness.The dynamic responses of the face gear system and the planetary gear system when the eccentricity error occured were solved,respectively.The dynamic behavior of the system under eccentricity error was characterized by time domain diagram,frequency spectrum diagram,bifurcation diagram and maximum Lyapunov exponent diagram,which revealed how eccentricity affected the complex gear transmission system's vibration characteristics.Results show that under the action of partial gear eccentricity,the vibration displacement of the corresponding meshing line displacement increases significantly,and the original periodic response changes to multi-periodic response.Due to the coupling effect of each part,the remaining meshing line displacement of the system fluctuates periodically under eccentric excitation,and the vibration displacement increases to varying degrees,and bifurcation replication occurs,which reduces the motion stability of the whole system.关键词
