| 摘 要： | 针对夹层约束阻尼梁结构的减振特性进行深入研究.应用粘弹性材料的耗能原理结合模态应变能法对局部粘弹性被动约束阻尼简支梁的振动特性进行数值分析,对梁铺设阻尼层前后的时域和频域特性分别进行比较,可以得出约束阻尼梁的振动得到有效抑制,同时看到模态应变能法对板梁结构的分析更便捷.

| Abstract: | Vibration analysis of beams with sandwich constrained layer damping treatment is extended .According to the elastic-viscoelastic principle and the modal strain energy method,an analytical approach for vibration response analysis of a beam with single passive constrained layer damping patch is presented. Parametric studies are performed with the established analytical approach to study the effects of constrained layer damping treatment. After compare between covered and uncovered beam in time domain and in f... |
