覆冰分裂导线舞动的ANSYS有限元分析法

ANSYS Finite-element Analysis Method Of Iced Bundle Conduct Galloping

为分析覆冰分裂导线舞动时的应力变化情况,研究导线舞动和指导连接金具设计,根据现有比较全面的三自由度导线舞动模型,利用ANSYS有限元软件建立了山西地区典型的紧凑型输电线路覆冰导线的舞动模型。利用该有限元模型对6分裂覆冰导线的舞动情况进行了动态仿真,输出了导线舞动时变化图像,可以直观的看到舞动时导线和间隔棒内部应力分布,为研究导线舞动及设计连接金具受力提供有力支持。

For the analysis of the variation of stress in iced bundled conductor,the research of conduct galloping and assistant design of connecting fittings, according to the more comprehensive existing three degrees of freedom conduct galloping model,using ANSYS finite element software established the model of compact transmission line iced conductor galloping in shanxi. By using this finite element model for dynamic simulation of six bundle iced conductor,this model can output the images of conduct galloping,also the internal stress distributing in galloping conductors and spacer can be intuitive view, provided strong support for the research of conductors galloping and the design connection fitting.
