Dynamic simulation and vibration test of tooth breakage fault for metro gearbox
Metro gearbox is a key component for torque transmission in vehicles
and its failure will directly affect the safety of train operation. The vibration characteristics of tooth breakage faults in metro gearbox were studied by combining dynamic simulation and vibration test. Firstly
based on the dynamic relationships and constraint characteristics between various components of metro gearbox
a rigid-flexible coupling dynamic model of metro gearbox with tooth breakage faults was established through the impact function method
Coulomb friction model
bearing modeling
flexible body of the housing and gear system dynamics theory. The dynamic response of the gearbox under different types of tooth breakage faults was studied
and the influence of operating parameters on the vibration characteristics of tooth breakage was analyzed. Then
through vibration test
the dynamic response of metro gearbox under normal state and broken tooth fault was obtained
verifying the accuracy of the dynamic simulation model. The results indicate that the rigid-flexible coupling dynamic model can effectively calculate the acceleration response of gearbox in different operating states
provide diagnostic basis for the prediction and identification of tooth breakage faults in the gearbox.
