摘要:
目的：随着城市轨道交通的快速建设，对城市轨道交通车辆的运行品质有了更高的要求。减轻簧下质量、改善小曲线半径通过能力、减小轮轨磨耗、降低运行噪声已经成为城市轨道交通车辆的主要研究课题。方法：结合内置轴箱转向架结构空间紧凑、质量轻、曲线通过性能好等特点，研发出一种适用于我国B2型地铁限界的内置轴箱转向架。重点介绍了列车速度为120 km/h时内置轴箱转向架的设计参数、结构组成及技术特点，对转向架构架强度进行了计算及验证，并对列车进行了动力学分析及线路验证。结果及结论：内置轴箱转向架具有质量轻、轮轨作用力低等技术优势，完全符合城市轨道交通车辆运行条件需求。
Abstracts:
Objective: With the rapid development of URT (urban rail transit), higher requirements are placed on the operation quality of URT vehicles. Reducing the unsprung mass, improving the small radius curve negotiation capability, minimizing wheelrail wear and reducing operational noise have become major research topics for URT vehicles. Method: Combining the compact structure, lightweight design, and excellent curve negotiation capabilities of the inboard axle box bogie, an inboard axle box bogie suitable for Chinese B2type metro clearance is developed. The design parameters, structural composition, and technical characteristics of the inboard axle box bogie for 120 km/h speed level are emphatically introduced. The strength of the bogie frame is calculated and verified, and the dynamics analysis and line validation of the train are conducted. Result & Conclusion: The inboard axle box bogie offers technical advantages such as lightweight construction and low wheelrail force, fully meeting the operational requirements of URT vehicles.
