摘　　要：为研究110kV带二分拉杆的FRP复合横担双回路输电塔受力性能,采用有限元软件ANSYS建立复合横担塔分析模型,了解不同工况下输电塔的受力状态,对整塔位移和杆件轴力进行分析,得到各种荷载组合情况下的塔体受力情况,并与角钢塔对比。结果表明:复合横担塔以90°大风工况为控制工况;各工况作用下,钢构件的最大应力约为300MPa,位于塔腿主材处,复合材的最大应力约141MPa,位于复合材料拉杆处,塔体应力在安全裕度内,满足强度要求。In order to study the mechanical performance of 110 kV new type composite cross-arm drum-type transmission tower,the finite element software ANSYS was used to establish the analysis and calculation model of the tower,to explore the stress state of the transmission tower under different working conditions,to analyze the displacement of the whole tower and the axial force of members,to obtain the force situation of the tower under various load combinations,and to compare with the angle steel tower.The results show that the tower is controlled by 90°strong wind.Under various working conditions,the maximum stress of steel is about 300 MPa,which occurs at the main material of tower leg,and the maximum stress of composite material is about 141 MPa,which occurs at the pull rod of composite material.The stress of tower body is within the safety margin and meets the strength requirements.
