利用ANSYS有限元分析软件对某洗衣机机箱进行了模态分析，得到了机箱的固有频率及相关振型。同时，对洗衣机机箱进行了谐响应分析，得到了机箱上某节点沿虚拟 X、Y 、 Z轴的位移－频率曲线，在此基础上分析得出低阶频率对洗衣机机箱振动特性影响较大的结果，并将分析结果与洗衣机脱水运转过程中的激振频率进行对比，得出了洗衣机在各种转速下的振动情况。

By using finite element software ANSYS ,the modal analysis for washing machine cabinet was performed ,the natural fre‐quency and vibration mode were also obtained .And a harmonic response analysis was carried out to get the displacement frequency curve of node along the virtual axis X ,Y ,Z .Based on this ,it is concluded that the effect of low‐order frequencies on vibration charac‐ter is stronger ,and the vibration of washing machine at all engine speeds was obtained by comparing the analysis result with the exci‐tation frequency of the washing machine in the process of dehydration .
