Abstract

An optimization method has been developed as a tool to contribute to the design of lightweight and high-rigidity automotive transmission housings. The method is divided into topology optimization and shape optimization and can be applied at any of three different stages depending on the maturity of the design.The application of topology optimization from the framework conception stage in the design of an actual automotive transmission enabled rigidity targets to be met with a reduction in weight of 10%.Study of the generation of stress in the optimized shapes predicted by the method indicated that the placement of ribs along the paths of transmission of bearing load to increase rigidity was highly efficient.
