摘要
提出了一种整体划分单元的有限元法来建立两种约束阻尼梁的有限元模型，根据阻尼结构的变形能原理推导得出了其刚度阵和质量阵。通过一个算例证实了本法可提高运算速度和计算精度．
A new finite element model with integrally divided elements, developed from the detailed analysis of energy dissipation in beams with constrained viSCoelastic bayers, is presented. Results acquired by the computer program designed with the above method are compared with those by analytical solution, and it is shown that the theory in this paper is more precise, more reliable and more economic.
