摘要
转向架是支承、牵引和制动车体并能相对车体回转的走行装置,具有缓冲振动和导向功能,决定列车运行安全可靠性和运行品质。中国高速动车组转向架经过技术引进、吸收创新和自主创新3个阶段的发展,通过不断的技术创新与实践,在结构轻量化、安全可靠性、动力学性能及智能化等关键技术上取得了成果,针对转向架结构强度和动力学性能开展的试验台、环形道、试验专线科学研究试验及线路长期服役跟踪测试,为自主创新阶段的中国高速动车组转向架的自主开发奠定了坚实的理论研究和工程实践基础。文章系统地回顾了中国高速动车组转向架在3个发展阶段的结构参数和技术瓶颈,指出了下一代高铁及CR450动车组转向架技术研究方向;从转向架基本结构角度系统论述了转向架总体集成、构架、轮对轴箱及定位装置、悬挂装置、驱动系统、基础制动和辅助装置的技术发展历程及趋势,提出技术自主创新及工程应用创新研究方向;论述了转向架轻量化设计、强度可靠性、车辆系统动力学、智能化设计和试验测试这5种关键技术的研究现状及发展方向。
Bogie is the running device that supports,pulls and realizes the brake of vehicle body,buffers vibration and rotates relative to the vehicle body,which determines the safety,reliability and quality of train operation.The bogie of China's high-speed EMU has undergone three stages of development:technology introduction,innovation based on absorption,and independent innovation.Through continuous technological innovation and practice,achievements have been made in key technologies such as structural lightweight,safety and reliability,dynamic performance,and intelligence.The scientific research and testing conducted on test benches,circular tracks,and dedicated testing lines for the structural strength and dynamic performance of bogies,as well as the long-term service tracking testing of the lines,have laid a solid foundation for theoretical research and engineering practice and the independent development of China's high-speed EMU bogies in the stage of independent innovation.This paper systematically reviews the structural parameters and technical bottlenecks of China's high-speed EMU bogies in three development stages,and points out the technical research direction of the next-generation high-speed EMU and CR450 bogies.From the perspective of the basic structure of bogie,this paper systematically discusses the development process and trend of bogie's overall integration,frame,wheel-set axle box and positioning device,suspension device,driving system,foundation braking and auxiliary device,and puts forward the research direction of technological independent innovation and engineering application innovation.This paper also discusses the research status and development direction of five key technologies:lightweight design of bogies,strength reliability,vehicle system dynamics,intelligent design,and experimental testing.
