| 摘 要： | 摘要：用减基法（RBM）结合有限元法、傅里叶变换和Newmark直接积分法，研究了压电层合板在机电耦合载荷下的瞬态响应。用层单元将层合板沿厚度方向进行离散，得到时间域内的运动方程，通过傅里叶变换得到波数域内的控制方程。应用Newmark直接积分法求解波数域内的位移和电势，并在Newmark法求解过程嵌入减基法，构造减基空间，把结构的等效刚度矩阵、质量矩阵和载荷列向量映射到减基空间降阶，得到减缩的Newmark增量式，从而快速求解得到原结构波数域响应，通过傅里叶逆变换得到时域内的响应。以PZT-5A/0°PVDF铺层两相材料复合压电层合板为算例,分析了机电耦合线载荷激励下,位移场和电势场的瞬态响应情况。计算结果表明，求解过程引入减基法能更快得到结构的瞬态响应，并保证了精度。
