【摘要】 以目前输电线路中常用的猫头塔为研究对象,采用有限元软件SAP2000为分析工具,对不同塔高、不同塔头宽度、不同根开的猫头塔进行模态分析,根据分析结果得到输电塔线体系中铁塔沿纵向与横向的第1阶自振周期计算公式。更多还原

【Abstract】 The mode analysis was performed of the common cathead transmission towers,with different tower heights,different breadths of tower heads and different lengths between tower legs with software SAP2000.The formulae of natural frequencies of the cathead transmission towers along the transmission line and cross the transmission line were presented through the mode analysis.更多还原
