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.
Multimodulation damper (MTMD) control technology is an effective passive control method that has emerged in recent years.MTMD overcomes the shortcomings of the traditional STMD (monotonic damper) that the control effect is unstable when the structure frequency is drifted, Which has a good application prospect in engineering.Through the calculation of the vibration buffeting in Yangpu Bridge under the control of MTMD, the background response is emphatically analyzed, and the various parameters of MTMD are studied respectively, Beneficial conclusion in the evaluation.
