金属/高聚物夹层阻尼板的阻尼特性及其应用

The Damping Characteristic and Application of the Damping Metal polymer Sandwich Plate

本文在制备出金属／高聚物夹层阻尼板的基础上，分析了影响夹层阻尼板损耗因子的一些因素，结果表明，温度和阻尼层厚度等对阻尼板损耗因子有较大的影响；另外在直流接触器中，将衔铁进行了阻尼处理。

In the paper,the damping metal polymer sandwich plate is prepared,and the effect of various factor of the sandwich plate is studied.Experimental results show that the loss factor is greatly influenced by the temperature and thickness of the viscoelastic layer.The armature switching is treated as damping in a relay,the vibration characteristics of the armature switching are discussed.
