摘要
本文根据电视塔结构具有旋转壳外形的特点，提出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系统的安装位置、数量及其振动参数进行了优化计算。优化计算结果表明。
A kind of semiactive manipulable TMD system was proposed in this paper according to characteristic of TVtower in shape of revolutionary shell. A computer software was worked out with the theory of revolutionary shell. On this basis, the optimal calculation for location, quantity and parameters of TMD system was introduced. The results of optimal calculation show that the manipulable TMD system has obvious vibration absorption effects.
