In this paper, the internal dynamic excitation of the gear pair in a helical gear reducer of bridge crane is numerically investigated, taking into account of time-varying mesh stiffness, comprehensive gear error and meshing shock. The integral finite element model of bridge crane reducer gearbox is built by ANSYS software using APDL language. The internal dynamic excitations are imposed on the contact line of gear pair to solve the dynamic response of the gearbox. Using the results of dynamic response as boundary excitation conditions, the acoustic boundary element model is established. The surface sound pressure of gearbox and the radiated noise of field points are solved with SYSNOISE software. In order to verify the feasibility of the simulation method, a vibration & noise test is carried out. With the constant center distance as well as the similar total transmission ratio, the surface sound pressure of gearbox and the radiated noise of field points are calculated with different modules and helix angles. The effects of module and helix angle on the noise radiation of the gearbox are analyzed and discussed. The results provide a useful theoretical guidance for the design of gearboxes.
