中文摘要：

在有限元软件ANSYS软件进行模态分析和静力结构分析的基础上，设计制作了一种家电用压电主动减振器。该减振器由压电陶瓷、Diamond—Shape位移放大机构构成。对该减振器进行了放大率的计算，其放大率可达3．30；并对减振器进行阻抗分析、低温性能检测及减振降噪测试。通过减振降噪测试数据表明，该减振器可对一定频段的家电振动与噪音起到抑制作用，最大可降低噪音32％。

英文摘要：

A new type of home appliances of shock absorber is designed based on the modal analysis and the static structure analysis of finite element software ANSYS software. This shock absorber is consisted of piezoelectric ceramic and Diamond-Shape displacement amplification. The magnification of the shock absorber is calculated to a- bove 3.30. Next test on the impedance analysis, low temperature performance detection, vibration and noise reduc- tion test are carried on. Test results show that the shock absorber can inhibit the vibration and noise of the appliance with certain frequency band, the maximum reduction can be 32 %.
