Abstract
A dynamic finite element model of gearbox housing is established. The internal and external dynamic excitations of gear transmission system are calculated by numerical simulation method, considering the gear time-varying meshing stiffness, damping and meshing error in the internal dynamic excitation, and the torque ripple of engine, bearing time-varying stiffness and damping in the external dynamic excitation. The dynamic forces of housing bearing seats are obtained by simulating and analyzed the rigid and flexible coupled multi-dynamics of inner gear transmission system. On this basis, the dynamic response analysis of housing is carried out using a mode superposition method, and according to the results of constrained modal analysis, the dynamic response characteristics of housing are studied in the time and frequency domains. The results show that the housing structure design is relatively conservative, the various response amplitudes are small so that the sympathetic vibration is not occurred in the use process, and it is sufficient for application requuirement.
