摘要:近年来,随着列车运行速度和电流传输密度的提高,弓网电接触状况正变得越来越复杂,对弓网电接触
理论与技术的系统研究提出了迫切要求。为此对弓网电接触中接触电阻、热效应、摩擦磨损性能及受电弓滑板材
料 4 个方面的研究现状进行了综述。主要结论为:1)对弓网接触电阻的参数观测、机理分析和数学模型仍需开展
大量工作,包括更为全面准确的电接触试验方法和诊断技术,以及更为科学合理的弓网接触电阻数学模型。2)弓
网电接触热效应的研究需继续加强。采用试验和仿真相结合的方法获取弓网载流摩擦时,滑板、接触线以及接触
面的温度及其分布值得进一步深入研究,特别是雨、雪等特殊气候条件对弓网热特性的影响。3)应重视开展更高
速度等级和电弧动态特性对弓网摩擦磨损性能影响的探讨;同时深入研究弓网磨损预测模型。4)继续研究和开发
新型复合受电弓滑板材料;在具体应用时,需根据不同列车运行的特定条件,选取满足该条件下关键性能要求的
滑板材料。

Abstract:In recent years, with the improvement of running speed and current density of train, the electric contact status
between pantograph and catenary is ing more and plex, which puts forward an urgent request for syste-
matic study on theory and technology of electric contact between pantograph and , we reviewed the
research advances in contact resistance, thermal effect, friction and wear characteristics, and materials for pantograph strip.
Main conclusions are drawn as follows: 1)The observation of parameters, mechanism analyses, and mathematic model of
contact resistance between pantograph and catenary still have a lot of work to be carried out. Proper test method and di-
agnostic technology of electric contact are required to be further discussed,while the mathematical model of contact
resistance needs more research. 2) The research on the thermal effect will continue to heat up. With the bin-
