| Summary: | Tunnel boring machine (TBM) reducers are important components of TBM's cutter-head drive system. In order to reveal the dynamic characteristics of the two-stage planetary gear transmission system of the TBM reducer, the influence factors such as tooth surface friction, the time-varying meshing stiffness, the backlash and meshing error of the two-stage planetary gear transmission system of the TBM reducer are considered. The torsional dynamics model of the two-stage planetary gear transmission system of the TBM reducer is established by the lumped parameter method, and its dynamic characteristics are solved and analyzed. The inherent characteristic analysis results show three vibration modes of the planetary gear train: rigid body vibration mode, torsional vibration mode and the planetary gear vibration mode; the vibration displacement of each gear and the dynamic meshing force between the gear pairs are obtained from the dynamic response analysis. The result lays the foundation for the dynamic optimization design of planetary gear trains. |
