摘　　要：针对真塔试验费用高昂、试验前必须进行仿真的问题,基于有限元分析软件ANSYS建立了500 kV的SZTG16直线塔空间三维模型,对模型进行了静力学分析,计算了模型的前3阶自振周期,比较了模型计算结果与真型塔试验数据。结果表明,有限元模型可较好地模拟铁塔试验时真实受力情况,同时研究了导线找形问题,并建立了一塔两线模型,为后续铁塔试验模拟仿真、铁塔改型等提供了依据。Because of high cost for transmission tower test,it is necessary to simulation research before prototype test.The spatial three-dimensional model of the SZTG16 500 kV line tower is established by using ANSYS finite element analysis software.The static analysis of model is implemented and the first three-step natural vibration period of the model is calculated.Comparison of model experiment with prototype tower test,the results show that finite element model can well simulate the force state of tower test.Finally,transimission line form-finding is studied simultaneously and the oblique parabolic model is established.Thus,it provides reference for similar engineering project.
