Reasonable arrangement of stiffeners is of great significance for improving the strength and stiffness of the transmission housing. Taking the transmission housing of passenger car as the research object, the strength and stiffness of the transmission housing were predicted by finite element method (FEM), and the rationality of stiffener arrangement was evaluated. Then the mechanical analysis of unreasonable stiffener was carried out, and specific optimization measures were put forward from the position, direction, quantity and size of stiffener, so as to improve the mechanical properties of the transmission housing. Finally, the finite element analysis and experimental verification of the optimization scheme were carried out. The results show that compared with the original scheme of the transmission housing, the strength of the optimization scheme is increased by more than 26%, the stiffness is equivalent, and the structure does not have the risk of cracking and resonance. The optimization scheme had passed the bench strength test, which verified that the proposed stiffener optimization measures are effective, and the stiffener optimization measures have certain engineering reference value.
