戈拉-
Hamilton ' s principle are used to obtain equations of motion, which are discretized using finite element method. the frequency dependent damping of viscoelastic layer is modeled using the golla - hughes - mctavish ( ghm ) method and the system is analyzed in the time domain. ghm increases the size of the original system by adding fictitious dissipation coordinates that account for the frequency dependent damping
本文採用ghm模型描述粘彈性阻尼材料的本構關系，根據哈密頓原理分別對附加主動約束阻尼層結構（ acld ）和主被動阻尼分離結構（ acupcld和acopcld ，其中acupcld結構是將壓電作動層貼于粘彈阻尼層的下面， acopcld結構是將被動約束層和壓電作動層分別貼于梁的上下表面）的梁結構建立了有限元模型，進而得到系統控制狀態方程。
