摘要
针对输电塔体系中的3种不同类型的构件采用了3种类型的杆件计算模型——桁架杆单元、索单元和预应力杆单元,计算了输电塔体系的动力特性,并与通常采用的简化模型进行了比较.计算结果表明,导(地)线及绝缘子对输电塔的动力特性有一定的影响,不可忽略,并宜作进一步的研究和试验.
In accordance with three kinds of member of the transmission line systems-tower, conductors and insulators, three kinds of model, including truss element, cable element and prestressed truss element, are usecd to calculate the three dimension dynamic characteristics of tower-conductor coupled systems. The compare of the result with the simplified model shows the influence caused by conductors and insulator can't be neglected.
