摘要
基于有限元分析软件ABAQUS建立220 kV重冰区铁塔2K21-ZBC3-27和2K31-JC1-18的三维模型,对其进行不同工况下的线性静力仿真计算。对此两基铁塔进行真型试验,记录不同工况下铁塔测点位移和应变值,试验结果表明铁塔整体强度满足规范和工程要求。对模型计算的节点位移和杆件静力应变与实际试验数据进行比较,结果表明,ABAQUS有限元模型模拟计算的铁塔节点位移和杆件静力应变与实际情况相符,采用梁—桁架单元能够较好地反映塔材应力变化规律。
Taking 2K21-ZBC3-27 and 2K31-JC1-18 as objects,it establishes spatial three-dimensional models of transmission towers used in heavy ice area based on ABAQUS system.Defining the linear static simulation models under different working conditions,it completes the experiments of the two towers,analyzes the displacements and strain values of the towers.The results show that the overall strength of the towers can meet the specifications and engineering requirements.It compares the simulation displacements and static strain the models with the experimental data.The analysis shows that the simulation data are similar with the actual situation,and the beam-truss element can reflect the stress variation law of tower materials.
