摘要
提出了粘弹性阻尼夹层板动力分析的两次渐近法，并在小变形线弹性理论基础上，导出了粘弹性阻尼夹层板结构的有限元动力公式，构造了阻尼夹层壳单元。本文最后通过夹层梁的计算及实验对该法进行了验证。
The dual asymptotic method of dynamic analysis of viscoelastic damping sandwich plate is developed. Based upon assumptions of small deformation and linear elasticity, the finite element formulas of viscoelastic damping sandwich plate, including sandwich element, are developed. Finally, the method is validated through laboratory experiment of sandwich beam.
