【摘要】 以江苏省某地使用的移动内爬插接景观塔(金轮)为研究对象，使用SolidWorks建立三维模型，结合有限元分析软件ANSYS Workbench进行模态分析。通过模态仿真分析，得到该插接式单管塔前6阶非零模态频率及各阶模态振型，其中结构的第1阶非零模态的自振频率为2.089 9 Hz,自振周期为0.478 s,符合建筑载荷规范中对自振频率与周期的要求，证明所建的插接式单管塔模型符合工程计算要求。仿真分析可为插接式单管塔的动态特性评定、风载与抗震性能分析提供依据。更多还原

【Abstract】 Taking the mobile internal climbing plug-in landscape tower(Golden Wheel)used in a place in Jiangsu province as the research object, the three-dimensional model is established by SolidWorks, and the modal analysis is carried out with the finite element analysis software ANSYS Workbench. Through modal simulation analysis, the first six non-zero modal frequencies and modal vibration modes of the plug-in single pipe tower are obtained, and the first non-zero modal natural frequency of the structure is 2.089 9 Hz, the natural period is 0.478 s, which meets the requirements of the building load code for the natural frequency and period. It is proved that the model of the plug-in single tube tower conforms to the engineering calculation requirements. The simulation analysis can provide a basis for the dynamic characteristic evaluation, wind load and seismic performance analysis of plug-in single pipe tower.更多还原
