摘要/Abstract

摘要： 通过材料的选择和纤维的缠绕方式提高了复合材料输电杆塔的力学性能，利用有限元分析法对玻璃纤维增强树脂基复合材料（GFRP）杆塔、碳纤维增强GFRP杆塔在标准检验荷载下的受力和变形情况进行对比分析。结果表明，碳纤维的加入可以有效提高复合材料杆塔的刚度，杆塔最大位移相对减小20 %；在此基础上，设计了纱丝螺旋缠绕结合单向布纵向缠绕的线型缠绕方式，计算不同缠绕角度复合材料杆体的等效模量，分析纤维取向对碳纤维增强GFRP输电杆塔力学性能的影响，确定最优纤维缠绕设计角度为纵向缠绕角20 °，螺旋缠绕角50 °~55（°）。

Abstract: In this paper, material selection and filament winding design were proposed to improve the mechanical properties of composite transmission towers. The stress and deformation of glass fiber-reinforced plastic (GFRP) towers and carbon fiber-reinforced plastic ones under a standard test load were analyzed by a finite element method. The results indicated that the stiffness of the composite towers was effectively improved by the addition of carbon fiber, and their maximum displacement decreased by 20 %. On the basis of these results, the design of yarn spiral wound combined with one-way cloth longitudinal winding was proposed, and the equivalent moduli of composite towers were calculated at different winding angles. The influence of fiber orientation on the mechanical properties of carbon fiber-reinforced plastic towers was analyzed. The optimum angle of filament winding designed in this work was determined as 20 ° for the longitudinal winding angle and 50 °~55 ° for the spiral winding angle.
