Simulation of Air-Gap Noise of New Energy Automobile Motor

摘要：

　　The simulation of Air-Gap Noise of the motor includes two aspects: near-field noise and far-field noise.Firstly,a three-dimensional solid model of the motor is built in CATIA,and then imported into HyperMesh to generate the grids of the motor Air-Gap.Then the meshing model in HyperMesh is introduced into Fluent CFD software in the form of.cas to calculate the near-field noise of the motor Air-Gap; Finally the meshing model is imported into the CFX CFD software in.cas format for transient calculation to obtain the boundary conditions of the acoustic boundary element,and the far-field noise of the motor Air-Gap is calculated with Lms Virtual Lab.
