【 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.
