摘要 为电力机车提供牵引动力的受电弓滑板与接触网导线是典型的滑动电接触摩擦副,二者在工作中存在电、磁、热、力多场耦合效应,复杂的多场耦合作用将影响弓网的受流质量和摩擦磨损性能,开展电气化铁路弓网接触多物理场耦合效应研究,对降低弓网运行维护成本,提高受电弓滑板和接触网导线使用寿命等具有重要意义。该文重点归纳总结了近些年来弓网系统在电、磁、热、力多场效应下的相关研究进展。结合列车实际运行工况,综述了弓网接触电阻、电弧、接触温度、电磁力和压力载荷等因素对弓网载流摩擦磨损性能的影响规律,针对多物理场作用下研究中存在的问题与不足,提出进一步研究和完善的意见。在此基础上,从提高弓网滑动电接触性能、保障列车安全稳定运行角度,采用弓网接触电阻、燃弧率及接触温度对电接触性能的评价进行阐述和探讨,以期对弓网电接触行为进行合理预测与评估,为进一步研究弓网滑动电接触多场耦合效应提供参考。

Abstract:The pantograph slide plate and catenary wire providing traction power for electric locomotives are typical sliding electric contact friction pairs, which have multi-field coupling effects of electric, magnetic, thermal, and force in work. The complex multi-field coupling effect will affect the current-carrying quality and friction and wear characteristics of the pantograph-catenary system. The research on the coupling effect of multiple physical fields in pantograph-catenary contact of the electrified railway is of great significance to reduce the operation and maintenance cost of the pantograph-catenary system and improve the service life of pantograph slide plate and catenary wire.
This paper uses the classification and induction method to summarize the research progress of the pantograph-catenary system under the multi-field coupling effect in recent years. The research contents include four aspects: electric, magnetic, thermal, and force. The influence laws of contact resistance, arc, contact temperature, electromagnetic force, and pressure load on current-carrying friction and wear performance of pantograph-catenary system were summarized. Suggestions for further research and improvement were put forward. On this basis, the evaluation of electrical contact performance according to the pantograph-catenary contact resistance, arcing rate, and contact temperature was discussed. The following conclusions can be drawn from the analysis: (1) The observation of contact resistance parameters and mathematical model research must be deeply explored, especially the influence of extreme climatic conditions such as cold, low air pressure, and significant temperature differences on the contact surface. (2) The research on arc erosion needs to be further improved and strengthened. The multi-field coupled arc erosion numerical model is established, and the multiscale, parametric, and quantitative research on the pantograph-catenary arc is carried out using numerical optimization. (3) Attention should be paid to the influence of magnetic field on the performance of pantograph-catenary sliding electrical contact, and the discussion on the regulation of external magnetic field on the performance of pantograph-catenary electrical contact should be carried out. (4) The research on life prediction and failure of pantograph-catenary sliding electrical contact under multi-field coupling should be strengthened, and the current-carrying wear mechanism and failure should be deeply explored. The mathematical model of life prediction and failure of pantograph-catenary electrical contact must reasonably predict and evaluate the electrical contact behavior. The research results can provide a practical reference for future pantograph-catenary sliding electrical contact development.
Substantial progress has been made in the research of pantograph-catenary sliding electrical contact. However, some problems still need to be deepened and improved continuously. In the future, new technologies represented by artificial intelligence, big data, and cloud computing will promote the integration and development of various disciplines and continuously broaden the innovation space to study the multi-field coupling effect of pantograph-catenary sliding electrical contact.
