开发了一个谱元模型来表示耦合压电晶片和梁系统 (CPBS) 的动态响应，其中单个或并置的压电晶片粘合到基础梁上。采用Mindlin-Herrmann杆理论和Timoshenko梁理论来表示基础梁的位移场。欧拉-伯努利梁理论和线性压电用于模拟压电晶片的机电行为。提出了 CPBS 的详细光谱元素公式。所提出的频谱元素的有效性分别通过时域和频域的数值例子得到证明。
A spectral element model is developed to represent the dynamic response of a coupled piezoelectric wafer and beam system (CPBS) in which either a single or collocated piezoelectric wafers are bonded to a base beam. The Mindlin–Herrmann rod theory and the Timoshenko beam theory are employed to represent the displacement field of the base beam. The Euler–Bernoulli beam theory and linear piezoelectricity are used to model the electro-mechanical behavior of the piezoelectric wafer. Detailed spectral element formulation for the CPBS is presented. The validity of the proposed spectral element is demonstrated through numerical examples in time and frequency domains, respectively.
