Abstract
The EMU's braking energy and braking level distribution have been analyzed based on data of the traction and braking data recorder(TBDR).It is helpful to further grasp the operation law of EMU,provide technical support for EMU's service and failure analysis.Based on the modular design and programming ideas,using LabVIEW object-oriented software platform,we have developed the visual analysis software oriented to EMU running information.This software can realize the train running status information query and the braking energy distribution statistics within any operation time,the total times of the train stops and the statistical functions of its brake level.The case study shows that the electric braking energy∶the resistance power consumption∶friction braking energy is about 7∶2∶1;braking level in low speed region especially 100 km/h the following changes frequently,and emergency brake is rarely used.And study on recovery of electric braking is great significance.
