| description | 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. |
