The numerical simulation research on structural acoustic radiation problem of gearbox is carried out based on FEM Method. This paper analyzes the vibration noise radiation characteristics of the cabinet structure in three conditions: without vibration noise reduction measures ,laying damping layer ,and laying damping layer together with absorption layer. The results play a guiding role for the structural acoustic design of the gearbox structure and the arrangement form of the acoustic material.
