Lightweight design of motor housing based on multi-load case topology optimization
The current goal of motor industry is to achieve lightweight and miniaturized structure,improve reliability,power density as well as intelligence,etc.At present,the demand of lighter and smaller motors in manufacturing industry is increasing because this can effectively save materials and space.The housing of a PMSM was taken as the research object and the stiffness,strength and modal finite element analysis of the prototype finite element model were carried out in OptiStruct.Also,the free modal tests of the motor housing were conducted to compare the test results with the simulation results to verify the accuracy of the finite element model.In order to achieve lightweight design,the topology optimization method was introduced in the conceptual design stage of the motor housing.Combining the space and internal layout of the motor,multiple load cases topology optimization design of the motor housing was conducted,achieving the goal of reducing the quality of the motor housing and improving the overall mechanical performance.
