The speed profile of a train plays an important role in energy consumption and resulting costs. industrial objective this work is thus to develop method reduce the consumed by over journey playing on driver commands (traction braking forces) while respecting punctuality constraints. First, rigid body approach (Lagrangian formalism) introduced characterise dynamics train. In particular, aerodyna...
New high-speed trains need modern energy management methods to reduce energy consumption. A fuzzy method based control method was used to solve this problem in this paper and evaluated the results on basis of data in Tehran metro line 3. Recovering the maximum amount of train kinetic energy when it is in the braking mode and optimal division of traction systems demand between energy storage sys...
OBJECTIVE To analyze the status of occupational stress in different types of train drivers. METHODS By using cluster sampling method, a cross-sectional study was conducted in 1 339 train drivers (including 289 passenger train drivers, 637 freight trains drivers, 339 passenger shunting train drivers, and 74 high speed rail drivers) from a Railway Bureau depot. The survey included individual fa...
The vigilance of the driver is important for railway safety, despite not being included in the safety management system (SMS) for high-speed train safety. In this paper, a novel fatigue detection system for high-speed train safety based on monitoring train driver vigilance using a wireless wearable electroencephalograph (EEG) is presented. This system is designed to detect whether the driver is...
The study of the simulation of a high-speed train control system has great significance for the realization of a train control system. This paper studied the basic theory of a high-speed train control system in China. Based on the theory and structure of HLA (High Level Architecture), multi-resolution modelling, simulation real-time management methods and the system architecture of a highspeed ...
