高耸电视塔结构的空间风振响应与优化控制

THE SPACIAL DYNAMIC RESPONSES OF WIND LOAD AND OPTIMAL CONTROL FOR TALL TVTOWER STRUCTURES

  • 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,可控TMD系统具有显着的减振效果。

     

    Abstract: A kind of semi-active manipulable TMD system was proposed in this paper according to characteristic of TV-tower 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.
