【摘要】 在动态载荷(地震、风载等)作用下,电容器塔架结构各组成构件将因变形位移而使其自身产生相应的内力;为保证直流滤波电容器塔架结构整体具有足够的强度和刚度,必须对其机械特性进行动力分析与计算。采用ANSYS有限元分析,首先对不同类型的电容器塔架结构进行了实体建模,然后对其分别进行了动态仿真计算,比较分析了结构主要几何设计参数、尤其是上部结构突变层对结构稳定性的影响,提出了结构几何参数的优化设计建议,为电容器塔架结构的设计与制造提供了依据。更多还原

【Abstract】 Under action of such dynamic loading as earthquake, wind load, etc.,the internal force is generated by each structure of capacitor tower due to its deformation and displacement. For assuring sufficient strength and rigidity of the complete tower structure of DC filter capacitor, the dynamic simulation and analysis on the mechanical properties of the tower must be performed. In this paper, different types of model of the capacitor tower structure are set up by the ANSYS finite element method, and then dynamic simulation calculation is made. The main geometry design parameters of the structure, especially the influence of abrupt layer at the upper structure on the structure stability, are compared and analyzed.At last, the optimum design suggestion the capacitor tower structure is proposed to provide evidence on the design and manufacture of the tower structure of capacitor.更多还原
