摘要

本文主要利用Beam188和Link180两种单元建立四分导联有限元模型，计算跨度对两种有限元模型约束端张力的影响，并对不考虑转动自由度的梁单元有限元模型进行分析。研究了弯曲刚度对约束端节点张力的影响，并将计算结果与杆单元的计算结果进行了比较。结果表明，梁单元有限元模型能较真实地模拟四分导联的受力特性。

Comparative study on the calculation results of finite element modeling of downlead of substation based on beam element and rod element

This paper mainly uses Beam188 and Link180 elements to establish the finite element model of four-split downlead, calculates the influence of the span on the restraint end tension of the two finite element models, and analyzes the finite element model of the beam element without considering the degree of freedom of rotation. The influence of bending stiffness on the tension of restrained end nodes, and the calculation results are compared with the calculation results of the rod element. The results show that the beam element finite element model can more realistically simulate the force characteristics of the four-split downlead.
