An optimization method has been developed to enable the design of lightweight and high-rigidity automotive transmission housings.
A double-layered structural mesh is used for modelling in this method to reproduce the airtight structure of the housing. This method has enabled rigidity targets to be achieved in an automotive transmission housing while weight has been reduced by 4 to 8%.
By studying the stress generation of the optimized shapes predicted by the method indicated that placing ribs along the paths of transmissions of the bearing load in order to increase rigidity was highly efficient.
