摘要/Abstract

摘要： 随着高速列车轻量化、高速化的趋势发展，风致安全及其控制问题愈发关键，基于线性轨道涡流制动器的横风安全主动控制方法可为风致安全控制提供新的思路。线性轨道涡流制动器常用于铁道车辆的非粘着制动，其在工作时会在转向架构架与钢轨之间产生垂向磁吸力，利用此特性将其作为主动控制作动器，并基于车辆-轨道耦合动力学理论，建立横风环境下高速列车主动安全控制动力学分析模型。结合高速列车的复杂非线性特点，采用模糊控制策略对线性轨道涡流制动器所产生的垂向磁吸力进行主动控制。研究结果表明，当强横风威胁到高速列车的安全行驶时，横风安全主动控制系统能够及时响应，降低列车迎风侧轮重减载率和转向架倾覆系数，从而提升列车的运行安全性。

Abstract: With the development of lighter carbody and higher operating velocity in high-speed trains, the research of crosswind safety and its control become more and more critical. The active control strategy based on linear track eddy current brake system to improve crosswind safety of high-speed trains can provide a new idea for crosswind-induced safety control. Linear track eddy current brake system is typically used to improve the braking performance, which will produce vertical attraction force between train bogie and rail. Therefore, the active safety control analysis model of a high-speed train subjected to strong crosswind is established based on the vehicle-track coupled dynamics theory, where the linear track eddy current brake system is served as actuator. Considering the complex nonlinear characteristic of high-speed train, the fuzzy control strategy is used to control vertical attraction force. The simulation results show that active crosswind safety control system can react immediately when the high-speed train has the risk of overturning caused by strong crosswind, and reduce the wheel load reduction rate and bogie overturning coefficient on the windward side of the train, furthermore, the crosswind-induced safety of high-speed train is enhanced greatly by this active control system.

Key words: high-speed train, crosswind safety, linear track eddy current brake system, active control, vehicle-track coupled dynamics
