Dynamic modelling of gear transmission system considering tooth flank spalling
摘要
Abstract
Addressing the issue that the current energy method cannot accurately describe the time-varying meshing stiffness of the gears with tooth flank spalling,resulting in the imperfect dynamic modelling method for the fault of gear transmission system,an improved energy method was proposed.Considering various types of tooth frank spalling,a time-varying meshing stiffness formula that consi-dered the tooth frank spalling was established.The established time varying meshing stiffness was intro-duced into a six-degree-of-freedom transmission system,creating a dynamic model of the gear transmis-sion system that could simulate the tooth frank spalling.The Newmark-β method was used for solving,the numerical simulation results were compared and analyzed with the experimental data to verify the accuracy of the established model.Based on this model,the influence of the main parameters of tooth frank spalling on the time-varying stiffness,the corresponding stiffness variation law and the frequency characteristics of the dynamic response were investigated.The results show that the secondary frequen-cy peak with a spacing of 10 Hz occurs on both sides of the characteristic frequency of the gear trans-mission system with tooth frank spalling.关键词
