摘要
针对真塔试验费用高昂、试验前须仿真的问题,基于有限元分析软件SAP2000建立了110kV等级中重冰区1YD-JC4耐张塔空间三维模型,对模型进行了线性屈曲分析和非线性屈曲分析,计算了模型在各个工况下的屈曲因子和最大荷载。结果表明,1YD-JC4耐张塔符合设计要求,可为后续杆塔试验模拟仿真、杆塔改型等提供依据。
According to the costliness of tower test and simulation before the test, finite element analysis software called SAP2000 is used to establish three dimensional model of 1YD JC4 tension tower of 110 kV in heavy ice areas. And then the model of linear and nonlinear buckling analysis is implemented. Finally, the buckling factors and the maximum load in various operating conditions are calculated. The results show that 1YD JC4 tension tower meets the design requirements, which provides the basis for simulation experiments of subsequent tower and tower modifications.
