摘要:
文章结合接触网覆冰分类的特点，分析了接触网覆冰的粘结力、抗拉强度等性质，根据相关研究成果建立了覆冰多弹孔模型和覆冰失效准则，利用有限元方法，建立接触网除冰工况模型，并进行了仿真验证。在此基础上，以我国高速铁路典型接触网为例，分析了不同机械冲击荷载作用下，不同额定张力覆冰接触网导线的典型点应力、抬升量和除冰率，为接触网机械除冰提供了理论支持。
Abstract:
This paper combined with the characteristics of classification of icing on catenary, adhesive property and tensile strength of icing on catenary are analyzed. According to the relevant research results, icing multiple bullet holes model and ice failure criteria are established,using the finite element method, model of deicing operation of catenary system is established, simulation verification is carried out. On this basis, taking typical contact network of high speed railway in China as an example, the stress, lifting capacity and corresponding ice removal rate of typical points in iced catenary wire with different catenary rated tension under different mechanical impact loadings are analyzed, on. provides theoretical support for mechanical deicing of catenary system.
