Design and Simulation Analysis of Hydraulic Braking System for High-Speed Superconducting Electrodynamic Suspension Train
摘要
High-speed superconducting electrodynamic suspension (EDS) train represent a pivotal advancement in future rail transit, offering ultra-high speeds, low noise, and minimal energy consumption. As the critical safety subsystem, the braking system’s performance directly governs train reliability and operational efficiency. This study addresses the operational characteristics of EDS train by: (1) Defining braking functions and configurations against technical parameters. (2) Designing hydraulic braking schematics. (3) Conducting functional planning and theoretical calculations of key braking parameters. AMESim-based simulations demonstrate: (1) Capability to execute 5 consecutive emergency brakes at minimum operating pressure (9 MPa). (2) Emergency braking response time < 0.5 s with solenoid valve flow area ≥ 3 mm2. (3) Discharge valve with φ1.5–φ1.75 mm orifice satisfy 10–20 s discharge requirements across pressure states. This research establishes a theoretical foundation and technical framework for engineering implementation of braking system in superconducting EDS train.
