| 摘 要： | 将状态空间法和微分求积法相结合，分析了压电-弹性层合梁的自由振动.
通过微分求积把状态方程在每一个节点处离散，进而求得解答. 选用不同的节点数目，
分析了方法的收敛性. 计算结果与相关文献的结果能较好地符合. 该方法
对于分析压电-弹性层合梁的工程振动问题非常方便.

| Abstract: | Free vibration of the piezoelectric-elastic laminated
beams is studied by combining the state-space method and differential
quadrature method. The state equations are dispersed at every sample point
by using the differential quadrature technique to obtain the solutions. The
convergence of the present method is also studied by choosing different
number of sample points. The obtained results are validated to show that the
developed method is convenient for vibration analysis of
piezoelectric-elastic laminated beams. |
