According to the structure and installation of large vertical planetary transmission gearbox, a finite element model were established based on FEM to carry out the vibration modal analysis and calculate the modal frequencies and stationary unbalance responses. A boundary element model of the sound field surrounding the gear box was established based on BEM to calculate and simulate the radiated sound pressure with the results of stationary unbalance responses. The results of testing and theoretical calculation are consistent, which indicates the rationality and accuracy of the theoretical calculation.
