Abstract
To reduce the vibration and noise of the face gear drive system，the second-order and fourth-order transmission errors，the contact path inclination and the contact ellipse major axis were preset．The face gear pair were modified，and the corresponding dynamics model was established. Taking the root-mean-square of the acceleration along meshing line as the optimization objective，the genetic algorithm was used to obtain the optimal active modification parameters． The bifurcation characteristics and the influence of meshing stiffness on system were analyzed．The results show that the root-mean-square of the acceleration after the optimization of the second and fourth-order transmission errors are reduced by 85.7% and 88.1% compared with theoretical value．The fourth-order transmission error has a better effect in damping vibration．The vibration is not only related to the mean value of the meshing stiffness，but the amplitude of the higher-order harmonics of meshing stiffness has a greater impact．Within a reasonable range of values，increasing the length of the contact ellipse major axis is beneficial to reduce vibration，and the angle of the contact path can be taken around 10.5° and 13.5°．Active modification can narrow the window of chaotic motion，which is beneficial to improve the system stability．The research results provide a theoretical basis for the vibration reduction design of the face gear pair.
