【摘要】 在电力行业迅猛发展的今天,角钢输电塔已经成为了目前主要的输电塔形式.其塔腿正面形式多采用三角形框架内部加以辅助材支撑形式,以减小其长细比.一般来说,转角塔会常用等分的支撑形式.本文利用结构力学的方法,结合实际线路工程中的塔腿形式,对其常用的两种辅助材支撑形式做了力学分析和比较,并且建立了ANSYS有限元模型,对其有限元分析结果与计算结果也进行了对比,以发现其各自的优劣所在.更多还原

【Abstract】 As the development of the electricity industries,the angle steel tower has become the major type of the electricity transmission tower.Its tower leg is usually made as a triangle steel truss,with the auxiliary truss supporting the inner structure so as to decrease its slenderness ratio.The inner auxiliary truss usually divided the triangle truss into equal parts.This passage made a comparison with two different types of the auxiliary truss which are most common in the tower leg.Several research methods were used in practice such as classical structural mechanics method,FEA software method and ANSYS to analyze the engineering case.更多还原
