中文摘要：

基于正压电效应的压电分流阻尼技术，具有简单，低功耗，轻便，易控制等优点，已广泛应用在结构被动控制中。在航空航天领域的应用中，考虑到加工和操作上的工艺限制，如附加质量、附加刚度、结构空间和成本等，提出了压电分流阻尼系统能量转化效能的概念。该文首先从理论上分析了系统有效机电耦合系数对压电分流阻尼抑振效能的影响．然后利用不同面积的压电元件进行薄板结构的振动控制，得到了不同目标结构的最佳抑振效果，计算出压电分流阻尼系统抑振效能与压电元件单位面积间的关系。结果表明，随着压电元件面积的增大，压电分流阻尼系统的振动抑制效果增加，而能量转化效率降低。因此，在实际应用中要权衡考虑系统能量转化效率和抑振效果以及附加质量等因素。

英文摘要：

Piezoelectric shunting based on the directly piezoelectric effect has been known as a simple, low-lost, lightweight and easily-to implement method for the passive damping control of structure vibration. In the aeronautical and aeronautical applications, considering of the operational and manufacturing constraints, such as added mass, maximum strain, structure space and cost, the concept about piezoelectric shunt damping effectiveness relative to the area of PZT transducer was proposed in our study. The effect of the effective electromeehanieal coupling coefficient k31 on vibration suppression was also analyzed. The vibration control experiment on clamped aluminum plate with passive serial R-L piezoelectrie shunt circuit was performed. And it clearly comes to a conclusion that the vibration control efficiency of piezoelectric shunt damping system deelines, which is followed the area of PZT transducers in- creased. However, it is much obvious that the amplitude reduction of plate was increased successfully. In practical applications, the effect of vibration eontrol,added mass,cost and other factors should be traded off.
