高耸闪蒸塔调谐质量阻尼减振技术的数值分析

针对高耸闪蒸塔在强风作用下振动响应过大的问题,将调谐质量阻尼器（TMD）减振技术应用到高耸闪蒸塔风振控制中,以保证设备运行安全并延长其使用寿命.通过Matlab数值模拟,研究了TMD安装后闪蒸塔顶端的风振能量减少率以及寻找最优参数.在此基础上,总结了能量减少率等值线图,可以通过协调二者的关系来解决TMD运行空间有限的难题.研究结果表明：TMD可以有效控制高耸闪蒸塔进行风振响应,在最优匹配参数下,TMD能够降低闪蒸塔的顶端振动能量约47.07％,为工程实际应用提供了一定参考.

Numerical simulation on vibration reduction of high-rise flashing column implemented with the tuned mass damper

Aiming at the problems of the wind-induced vibration of high-rise flashing column,the tuned mass damper （TMD） was researched to minimize the vibration,ensure safety operation and prolong service life.By numerical simulation,the top vibration energy decrement rate of the equipment with the TMD and optimal matching parameters of the TMD had been studied.The contours of the energy decrement rate were presented to solve the problem of limited running space of TMD.The results indicate that the TMD is feasible for wind-induced vibration control of high-rise flashing column,and that the top vibration energy reduces by 47.07％ under optimal matching parameters,which has provided valuable preferences for practical application.
