摘要

摘要: 隔膜抽气泵在运转过程中会产生振动，使用阻尼垫片可以有效减小其振动。设计并制备了一种三明治约束阻尼垫片，其约束层使用铝合金，阻尼层采用黏弹性材料。通过时域和频域响应分析对比了三明治约束阻尼垫片安装前后隔膜泵的振动响应，发现该垫片能够以4 mm（或传统的1/10）厚度实现良好的减振效果，提高了系统的稳定性。与此同时，本文还从材料和结构的角度分析了三明治约束阻尼垫片的减振机理。

Abstract: Diaphragm air pump will produce vibration during operation. The constrained damping gasket (SCDG) can effectively reduce the vibration of the diaphragm air pump. A SCDG is designed and prepared in this paper, in which the aluminum alloys as the constrained layer and the viscoelastic materials as the damping layer. The vibration response of the diaphragm air pump with and without SCDG was compared through the time-domain and frequency-domain response. It is found that the SCDG can achieve good damping effect with 4 mm (or 1/10 thickness of traditional gaskets) as the thickness, thus improving the stability of the system. At the same time, the damping mechanism of SCDG is analyzed from the aspects of material and structure.
