摘要

基于压电元件的主动振动控制不仅需要复杂的信号处理系统

而且需要庞大的能量供给系统;被动控制中电感和电阻参数对环境变化适应能力差

而且低频控制时需要很大的电感

不容易实现。为了克服主被动控制存在的缺点

提出了一种基于同步开关阻尼技术的半主动振动控制的新方法。利用TMS320F2812处理器

通过合理的开关控制算法

使埋入复合材料悬臂梁约束端的压电元件上的电压极性在适当的时候进行翻转

使其电压始终与应变反相

从而达到振动控制的效果。实验结果表明

该方法可以使悬臂梁一阶振动模态减小3.164 1 dB。

Abstract

Application of active vibration control system based on piezoelectric elements in real-world structures is limited by its requirement for complicated signal processing system and bulky energy supply system;the passive vibration control system is also difficult to implement its system paramenters of inductance.Moreover

the resistances in this system are sensitive to environment

so that it needs large inductance to control low frequency vibration. In order to overcome these drawbacks

a new method of semi-active vibration control based on a technique of synchronized switch damping has been developed recently. By using the processor of TMS320F2812 and the logic switch control algorithm

the polarity of the voltage on a piezoelectric element embedded in cantilever composite beam can overturn at proper time

so that the vibration controlling effect is achieved due to the opposite directions of the voltage-induced force and the strain rate. The experimental results show that the first mode of the cantilever beam can reduce by 3.164 1 dB.
