摘　　要：碳纤维复合芯导线抗弯、抗侧压、抗扭性能差,故要求1660 mm2碳纤维导线用放线滑车底径较大。若采用传统经验方法设计,将导致放线滑车质量较大、设计周期长、研发成本高等问题。针对放线滑车主要部件滑轮,进行了材料分析研究,提出了优化约束条件,并利用ANSYS软件建立滑轮仿真模型,通过调整滑轮材料、结构尺寸参数等方法,完成滑轮设计,并对滑轮进行试制试验。通过有限元分析结合试验的方法得到了满足工程强度、刚度要求且质量较轻的放线滑车滑轮。与传统经验设计方法相比,滑轮减重约23%。研究结果可为输电线路放线滑车滑轮设计提供参考依据。Aluminum Conductor Composite Core(ACCC)has poor bending resistance,lateral pressure resistance and torsion resistance.Therefore,it is required that the diameter of the stringing block for 1660mm2 ACCC is large.If the traditional empirical method is adopted for design,it will lead to problems such as heavy stringing block,long design cycle,and high research costs.In this paper,the material research of the sheave was carried out,and the qualification criteria were proposed.The sheave simulation model was established by using ANSYS,and the sheave optimized design was completed by adjusting its material and structure size.In order to verify the reliability of the optimized design scheme,manufacture and test of the sheave,through the method of finite element analysis and test,a light-weight sheave that meets the requirements of strength and stiffness was obtained.Compared with the traditional empirical design method, the weight loss of the sheave is about 23%. The research results can provide reference for the design of sheaves of overhand transmission line.
