摘　　要：将质量矩阵和时间积分法引入压电扩展逐层法(XLWM,extended layerwise method)中,根据压电片和复合材料层合结构连接区域的位移和内力平衡条件,建立了含压电复合材料层合板总体控制方程,实现了含损伤结构的瞬态响应分析。在数值算例中:首先,利用无损伤结构开展了收敛性分析,并将收敛后的结果与ANSYS软件模拟的三维弹性模型进行对比,以验证所提方法的正确性;其次,研究了含有单一损伤的情况下,不同损伤参数对含压电复合材料层合板瞬态响应的影响规律;最后,研究了多损伤情况下含压电复合材料层合板在不同损伤参数下瞬态响应的变化规律,并分析了压电片与复合材料耦合位置对瞬态响应的影响。The mass matrix and time integration method were introduced into the piezoelectric extended layerwise method(XLWM).According to the displacement and internal force balance conditions of the connection area between piezoelectric sheet and composite material laminated structure,the overall control equation of piezoelectric composite material laminates was established,and the transient response analysis of structures containing damage was achieved.Firstly,in the numerical example,the convergence analysis was conducted using non-destructive structures,and the converged results were compared with the three-dimensional elastic model simulated by ANSYS software to verify the correctness of the proposed method.Secondly,in the condition of containing single damage,the influence law of different damage parameters on the transient response of piezoelectric composite material laminates was studied.Finally,under multiple damage conditions,the variation law of transient response of piezoelectric composite material laminates under different damage parameters was studied,and the influence of the coupling position between piezoelectric sheet and composite material on the transient response was analyzed.
