| 摘 要： | 多重调质阻尼器(MTMD)控制技术是近年来兴起的一种有效的被动控制方法.MTMD克服了过去常采用的STMD(单调质阻尼器)在结构频率发生漂移时控制效果不稳定的缺点,在工程上具有良好的应用前景.本文通过对杨浦大桥抖振在MTMD控制下的计算,着重分析了考虑背景响应的情况,对MTMD的各个参数分别进行了研究,得出了一些在MTMD设计和评价中有益的结论.

| Abstract: | MTMD (multiple tuned mass damper) is a new efficient technology in passive control to structure's vibration. MTMD method can improve the shortcomings of STMD(single tuned mass damper) that the control efficiency may be varied when the frequency of structure changes. In this paper, a detailed calculation of buffeting response composed of resonant part and background part of YangPu bridge under the control of MTMD is presented, and the effects of the parameters of MTMD on the control efficiency are discussed in detail. |
