Research on Low-Floor Tram Brake System Control
Journal Title: Urban Mass Transit - Year 2024, Vol 27, Issue 10
Abstract
Objective The traditional brake control system adopts the train braking control unit host for mechanical braking control, featuring high cost and inability to coordinate reasonable integrated management of electro-hydraulic braking. In order to fully grasp the control principles and functions of the brake system, and to reduce system complexity and cost while ensuring reliable performance, it is necessary to conduct a comprehensive and in-depth research on the control scheme of the low-floor tram brake system. Method Based on the German HANLING & KAHL brake system used in a low-floor tram project in Europe, a deep research and analysis of the system is conducted for the design of an electrical control principle and control scheme of the low-floor tram brake system. By comprehensively introducing the braking function, braking method, and braking mode of the low-floor tram brake system, the composition, principle, and electrical control schemes of electric braking, hydraulic braking, and magnetic rail braking are described in detail. Combined with the vehicle brake control logic of the project, the electro-hydraulic coordination logic and brake control scheme of the brake system under various operating conditions are comprehensively explained. Result & Conclusion The brake system control scheme has been tested, verified and widely applied on European trams, showing no system control function failures in many years operation. It has the characteristics of excellent performance, high reliability, low cost, and clear control logic.
