摘　　要：与传统金属材料相比较,纤维增强树脂基复合材料具有比模量大、强度高、耐化学腐蚀、可设计性强等许多优异特点,是输电杆塔结构材料的理想选择。以复合材料电杆为研究对象,利用数值模拟方法,对不同的纤维铺层角度、铺层数目、含碳百分数等结构参数进行了分析,并获得了电杆顶端位移和结构极限承载力,给出了电杆结构增强方法。结果表明:铺层角取25°~35°,刚度可提高18%~37%,极限承载力可提高约30%;铺层数为12~14,刚度可提高约20%,极限承载力可提高约25%;建议加入碳质量分数为10%,刚度可提高约16%,极限承载力可提高约17%。Compared with traditional metal materials,fiber reinforced resin matrix composites have many excellent characteristics,such as large specific modulus,high strength,chemical corrosion resistance,strong designability and so on.In this paper,the composite pole are analyzed with different structural parameters,such as different fiber ply angle,ply number and carbon content percentage by using the numerical simulation method.The top displacement of the pole and the ultimate bearing capacity of the structure are obtained,and the reinforcement method of the pole structure are given.The results show that when the ply angle is 25°to 35°,the stiffness can be increased by 18%~37%and the ultimate bearing capacity can be increased by about 30%;when the number of layers is 12 to 14,the stiffness can be increased by about 20%and the ultimate bearing capacity can be increased by about 25%;it is suggested that the mass fraction of carbon is 10%,the stiffness can be increased by about 16%,and the ultimate bearing capacity can be increased by about 17%.
