洗衣机机箱模态试验研究

本文将现代测试手段和模态分析技术相结合,应用试验模态分析方法对某全自动滚筒洗衣机机箱进行了模态试验,得到其固有频率、模态振型等模态参数。测试结果分析表明,该机箱左右两侧面及其后面存在较为严重的振动问题,并对此提出相应的改进措施。

Model Test Study on Washing Machine Cabinet

Based on the combination of modern testing methods and modal analysis technology,this paper uses experimental modal analysis method to test the intrinsic characteristic of an automatic drum washing machine cabin and gain its natural frequencies,mode shapes.The measured results show that the vibrations on the left,right and back sides of the cabinet are serious and some improving suggestions are proposed.
