摘　　要：运用ANSYS软件建立了三塔两跨塔线体系试验模型及其原型的有限元计算模型,并对它们在各种脱冰工况下的瞬态响应进行了分析和比较.结果表明,不仅响应的特征参数满足动力相似,而且整个时程响应曲线吻合良好,模型试验结果能够反映原型的动力特性,试验数据具备良好的互推性.本文的研究和结论不仅验证了试验模型设计的正确性,而且为试验模型的制作以及脱冰跳跃模型试验提供了理论指导.Using the commercial software of ANSYS, the dynamic analysis of three tower double span test model and its prototype is conducted, and their transient responses under various ice shedding conditions are compared. It is shown that not only the characteristic parameters of ice shedding responses are all similar, but also the whole time history curves fit well. Therefore, the test results of the model are valid, and they reflect the dynamic properties of the prototype. The study and the found in this paper not merely verify the accuracy of the test model, but also provide theoretical guidance for the model construction and the model experiment of ice shedding.
