摘要

针对Kagome夹心板的多模态振动控制问题,本文提出了一种独立模态压电分流振动控制方法。首先建立了结构与压电换能器耦合系统的有限元模型,之后详细阐述了Kagome夹心板的独立模态压电分流振动控制策略,并针对自由振动问题提出了一种实用的多分流电路参数优化方法。结果表明:文中提出的控制方法能显著提高Kagome夹心板结构的阻尼特性,加快自由振动的衰减,同时各压电分流电路之间具有很好的独立性。

Abstract

In this paper, aimed at multi-mode vibration control problem of the Kagome sandwich panel, a kind of independent modal piezoelectric shunt vibration control method was proposed. First, finite element model of the structure and piezoelectric transducers coupled system was established, then independent modal piezoelectric shunt vibration control strategy of Kagome sandwich panel was described in detail, while a practical multi-shunt circuit parameter optimization method for free vibration problems was also presented. The results show that the control method proposed in this paper can significantly improve the damping characteristics of Kagome sandwich panel structure, and accelerate the attenuation of free vibration. At the same time, the piezoelectric shunt circuit has good independence with each other.
