Abstract
The mathematical representation of fluid-structure interaction was deduced for a gearbox housing of composite transmission of a certain vehicle. And the fluid-structure interaction finite element model of a complex gearbox's housing was built. The effect of the oil height on the modal of the housing was analyzed, the exciting forces of the housing were analyzed and applied to the model; the vibration of the housing was calculated by the model, and the strength of housing was analyzed by the fourth material strength theory; according to the calculated results, the housing was strengthened by reinforcing ribs and the vibration of the modified housing was calculated. The calculated results show that the stress and vibration amplitude of the modified housing are lower.
