摘要
本文以江苏省无锡供电设计院设计的220kV HSZ窄基直线塔为工程背景,利用ANSYS软件建立窄基铁塔的有限元分析模型,并对该塔进行模态分析,得到窄基铁塔的前10阶自振模态及其相应的自振周期,从而更进一步了解窄基铁塔的动力特性。
This paper based on the 220 kV Dual-circuits Narrow base Transmission Tower, designed by Power Design Institute of Wuxi, Jiangsu Province for engineering background. Using ANSYS software to establish the finite element analysis model and carry on the Modal analysis of the Narrow base Transmission Tower. We have obtained its first 10 order modes and natural vibration period, thus it is better to understand the Dynamic char- acteristic of the Narrow base Transmission Tower.
