摘要
通过电流型运算放大器组成第二代电流传输器与RC元件实现模拟电路的设计,由此搭建压电分流阻尼系统控制机械结构振动。通过软件仿真测试模拟电感电路设计的正确性,并以根部粘贴压电陶瓷片的固支梁结构为例,对该结构的第三阶模态振动控制进行了实验研究和分析,结果表明:所设计的新型压电分流电路具有良好的减振效果。
Design of inductance simulators using second-generation current conveyor and RC components, and second-generation current conveyor composed of current-mode operational amplifier.From this design to set up piezoelectric shunt damping system to control mechanical structure vibration.Through software simulation test the correctness of the simulation inductance circuit design.Furthermore,with an example of clamped-clamped beam bonded piezoelectric patch, the third natural frequency of the beam is targeted to be controlled,and the experiment research is performed. The experimental results show that the design of new type piezoelectric shunt circuit has good vibration damping effect.
