Abstract: The test research on the noise causes of the washer machine motor is discussed in the paper, and to determine the mechanical noise is the main reason. A modal analysis with pre-stress of the entire motor structure is established by ANSYS software, and the weakness positions of the motor structure are found by FEA simulated analysis. The practical sound tests of the washer machine are run to verify the simulated result, and reduce the motor noise in the washer machine. The modal calculate and analysis results provide the reference standard for structural design and realize the project optimization.
