| 摘 要： | 粘弹性阻尼器 (VED)是减振被动控制中一种十分有效的耗能减震装置。VED的安装位置优化可使VED发挥最佳减震效果 ,然而通常要通过多次循环计算才能确定VED的优化位置 ,计算十分耗时。对多种位置优化目标函数及其实现方法进行了讨论 ,并根据VED的耗能原理及抗震规范提出了VED位置优化实用方法 ,使全部VED能够一次定位 ,简单可行 ,最后比较了VED在不同位置布置下的减震效果

| Abstract: | VED is a kind of efficient passive control device for suppressing vibration and dissipating energy.By optimizing location,VED could bring better effects of suppressing vibration.But defining optimal location of VED usually need many circular calculations,so it costs much runtime of computer.In this paper,several objective functions and their implementing method are analyzed in detail.And combined with building code a convenient method about choosing position of viscoelastic dampers is put forward based on principle of VED dissipating energy and thus the locations of all VEDs can be decided at once.The effects of suppressing vibration for different location of viscoelastic dampers are compared. |
