Dynamic Simulation and Analysis of Large-scale Gear Reducers

This study has established the equivalent CAE model of a loading large-scale gear reducer for simulating and evaluating the dynamic responses, including the rotation speeds of shafts and meshing forces of gear pairs, in the time and frequency domains by using MSC. ADAMS. The transient response results were compared with measurement data under the practical application to verify reliability and equivalence of the constructed CAE model. The proposed approach and model may be served as the basis to access the transmission performance, vibration analysis, failure diagnosis and even structure improvement for the large gear reducers.
