| 摘 要： | 针对楼板振动控制技术,文中介绍了两种阻尼器法,即附加粘弹性夹层板和调谐质量阻尼器(TMD)。采用有限元分析方法,对比了基础楼板、基础楼板+橡胶层、基础楼板+橡胶层+钢板以及基础楼板+TMD四种楼板形式的振动特性。结果表明,粘弹性约束阻尼层和TMD均可以有效衰减楼板振动加速度,而粘弹性约束阻尼层相比TMD可以在更广的荷载频域范围发挥更明显的减振作用。

| Abstract: | This paper introduces two kinds of damper methods for floor vibration control technology-viscoelastic sandwich plate and Tuned Mass Damper(TMD).In the paper,the vibration characteristics of four kinds of floor forms are compared:foundation floor,foundation floor+rubber layer,foundation floor+rubber layer+steel plate and foundation floor+TMD using finite element analysis method.The results show that both viscoelastic constrained damping layer and TMD can effectively attenuate the acceleration of the floor.Furthermore,compared with TMD,viscoelastic constrained damping layer can play a more obvious role in reducing vibration in a wider frequency domain. |

| Keywords: | vibration control of floor viscoelastic damping layer constrained damping layer |
