چکیده
Train passenger door is the key system for operation and maintenance on urban rail train. In this paper, we analysis passenger door system of urban rail train working process and establish the mathematical model. Firstly, we use the method of parameter estimation to get physical parameters of doors on different working condition. Then fault diagnosis experiment is done to train passenger door with principal component analysis and rough set theory. In the end, we verify fault diagnose accuracies under different time settings of opening and closing profile with the test rig.

The train derailment is one of the major accidents in rail transit safety system. The reach uses collision accident of rail transit train in Tokyo and Shanghai as the case. Firstly, it present fishbone diagram to qualitatively analysis main factors in derailment. Then it set up a derailment accident tree model with the qualitative and quantitative analysis of. The results show that illegal oper...
متن کاملOptimizing Urban Rail Timetable under Time-dependent Demand and Oversaturated Conditions
This article focuses on optimizing a passenger train timetable in a heavily congested urban rail corridor. When peak-hour demand temporally exceeds the maximum loading capacity of a train unit, passengers may not be able to board the next arrival train, and they may be forced to wait in queues for the following trains. Based on time-dependent, origin-to-destination trip records from an automati...
متن کاملOrigin-destination dependent train scheduling problem with stop-skipping for urban rail transit systems
The train scheduling problem with the origin-destination (O-D) dependent passenger demands is considered for urban rail transit systems. In this paper, trains are allowed to skip any intermediate stations (except the origin station and the final station) to reduce the passenger travel time and to save energy consumption. A model of train movements with stop-skipping and the O-D dependent passen...
متن کاملOptimal design of onboard energy storage systems with volume limitation for urban electrical rail transportation
Train braking energy regeneration in urban electrical rail transportation systems can reduce energy consumption and operational cost of the system. In this paper, optimal design of an onboard energy storage system (OESS) with volume constraint is presented for urban electrical rail transportation systems (ERTS). Onboard super-capacitors are considered as the storage system. The objective functi...
