【摘要】 本文研究了一种新型橡胶基压电复合阻尼减振材料。这种材料由PZT压电陶瓷材料、乙炔碳黑导电材料和溴丁基橡胶材料，经复合加工而成。在它的阻尼减振机理中，不仅保存了传统粘弹性阻尼减振材料的原子与原子间、分子链段之间以及填充剂与分子链之间的摩擦耗能机制，更重要的是利用压电组份PZT材料的压电效应，将系统振动的机械能转换成电能，再通过导电组份碳黑导电材料与橡胶基体形成的导电通路，进一步将电能转变成热能耗散掉。从阻尼系数的测试结果来看，这种新型的阻尼减振材料的阻尼减振效果优于国内外同类产品，而且其阻尼系数可通过改变系统振动的强弱而改变。更多还原

【Abstract】 A new type of smart vibration supression material were studied in this paper. Being a composite of three main components of Piezo-electric ceramic material PZT, electric conducting material Acetylene black and Br-butyl-rubber, this material is obtained through a production process similar to the traditional rubber fabrication process. Comparing with the energy dissipation mechanism of the traditional vibration supression material, in which the energy of external vibration is dissipated in a way of frications between atoms and molecules of it, a new type of energy dissipation mechanism is introduced into this new vibration supression material in addition, through which the vibration energy is dissipated by a great unumber of micro-electrical circuits formed in it. In this material, the vibration energy is firstly transformed into electrial energy by Piezo-electric material, and then is dissipated by the micro-resistors formed by the Carbon Black and the rubber materials, So the vibration energy is transformed into heat energy and lost. The damping coefficent testing indicats that the vibration supressing effect of this type material is much better than any other vibration supressing materials of this type in and out the country.更多还原
