摘要
根据高耸造粒塔结构具有旋转壳外形的特点，提出了一种环状半主动可控调频质量阻尼器（ＴＭＤ）系统．并以旋转壳理论编制了有限元程序。对ＴＭＤ系统的振动参数进行了优化计算，结果表明，可控ＴＭＤ系统具有显著的减震效果．为结构震后修复提供了一种经济、方便、适用、快捷的新途径．
A kind of semi-active controllable TMD system is proposed in this paper according tocharacteristic of grain -making tower with the shape of revolutionary shell. A computer softwareare worked out using the theory of revoluationary shell. On this basis, the optimal calculation forparameters of TMD system is introduced. The results of optimal calculation show that thecontrollable TMD sysem have obvious shock absorption effects. It provides a kindof economical, convenient, suitable and rapid method for structural renovation after earthuqkae.
