摘要
本文主要讲述最小二乘复频域法在洗衣机外壳、滚筒的模态测试上的应用及测试方法,通过对模态测试结果的分析,找到结构振动的原因并对振动问题提出优化方案,使洗衣机整体振动情况得到改善。
        In this paper, the application of least squares complex frequency domain method(LSCF, also called PolyMAX as a commercial name)in the washing machine shell and drum modal testing is analyzed. By analyzing the modal test results, the cause of structural vibration is found out and the optimization scheme of the vibration problem is proposed so that the overall vibration of the washing machine is improved.
