摘要
研究了具有弹性夹层的层板结构的振动特性。导出了双层板—弹性夹层的综合单元刚度矩阵。用这种综合单元刚度矩阵与普通板单元刚度矩阵对立柱结构的振动特性进行了有限元法计算对比。提出的方法与原理为精确分析具有多子结构的复杂机械结构的振动特性提供了有效手段。
The vibration behaviour of sandwich structure with spring interlayer is studied.The stiffness matrix of synthetic dual plate-spring interlayer element is deduced. Based on this kind of matrix and the one of ordinary plate element individually, the vibration behaviour of a column structure is calculated and the results are compared. The presented method and principle can be used as the effective means for precisely analyzing vibration behviour of complicated mechanical structure with multi-substructure.
