摘要：

In order to research the the effects of conductor wires on transmission tower under wind load, considering the theory of flat cable assumptions, the vibration equation of transmission tower-line system under wind load was deduced. Using software ANSYS, The 3-D finite element models of single tower, one tower and two spans of conductor wires, three towers and four spans of conductor wires, five towers and six spans of conductor wires were established separately, which were based on Qixia similar to Wendeng (Kunyu) 500kV transmission line project. Time histories of wind speed acting on transmission tower-line system were simulated with AR method using software Matlab. The displacement of middle towers in every model were caculated and analyzed. This paper discusses the effect of the tower-line interaction on the transmission tower-line system and derives some useful results, which is useful for the future research.
