| 摘 要： | 基于虚功原理,提出了一种新的建立主动约束阻尼板动力学模型的方法。该方法采用层合理论推导出约束阻尼板结构的动力方程,用GHM(Golla Hughes McTavish)方法引入辅助的耗散坐标,来描述粘弹性材料随频率变化的特性,并采用LQR方法控制结构的振动。其有效性通过算例进行了验证。同传统的有限元建模理论比较,采用层合理论,减少了结构自由度,并且具有良好的计算精度。

| Abstract: | Based on virtual work principle, a new modeling method for sandwich plates with viscoelastic core is presented. This method is developed using laminated theory. The damping of viscoelastic properties is modeled by the Golla-Hughes-Mc-Tavish (GHM) method and the frequency dependent behavior of the viscoelastic Material is described through the dissipation coordinates. Moreover, linear quadratic regulator (LQR) is explored for the active constrained plate. The effectiveness of this method validated by numerical model. This method can reduce degrees of freedom adequately and improve accuracy, compare to conventional finite element method. |
