摘要
重载列车是现代轨道交通运输中的重要运载工具,是煤炭、化石等矿产资源运输的主干力量。随着列车编组长度不断增加和轴重不断提升,其动力学与行车安全性问题日益凸显,制约了重载铁路运输能力与技术的发展。为了提升重载列车系统的动态服役性能,保障列车运行安全性,本综述阐明了重载铁路运输面临的动力学与行车安全性问题,系统梳理了重载列车系统动力学的研究现状,研究了列车纵向动力学、三维列车动力学和列车与轨道耦合动力学的分析理论与研究方法,分析了现有研究的不足及面临的挑战,探讨了其未来研究重点和方向,以期为重载列车技术的发展提供参考。
The heavy-haul train is an important type of modern rail transit vehicle,which is the main mode of transportation for mineral resources such as coal and fossils.With the increase in train length and the improvement of axle load,the problems of dynamics and running safety become more and more prominent,restricting the development of heavy-haul railway transportation capacity and technology.To improve the dynamic service performance of the heavy-haul train system and ensure the running safety and reliability of trains,the main problems of dynamics and running safety and challenges in Chinese heavy-haul railway transportation are clarified,the current situation of dynamics research of the heavy-haul train system is systematically reviewed;the analysis theory and research methods of longitudinal train dynamics,three-dimensional train dynamics,and train-track coupled dynamics are studied.Moreover,the shortcomings and challenges of existing research are analyzed,and the future research focuses and directions are discussed,which intends to provide a reference for the development of Chinese heavy-haul train technology.
