摘　　要：压电阻尼技术有两种类型:压电被动阻尼技术和压电主动阻尼技术.本文对其中的压电被动阻尼技术进行了研究.结果表明:通过给压电元件并联适当的外部电路,可使压电系统具有与粘弹阻尼材料及动力吸振器相似的物理特性.合理配置电路参数,可以实现最优阻尼比.Piezoelectric damping technology has two types, passive damping technology and active damping technology. This paper made a research on the passive damping. The results showed that the piezoelectric system with the physical properties in similar to viscoelastic materials and dynamic bumper, can be achieved through a suitable external circuit in parallel with piezoelectric element, and the optimal damping ratio can be reached with fitting correct circuit parameters.
