Safety Analysis for High Speed Bogie Technologies of CRH3 EMU
Advanced Materials Research, 2012The bogie technology of the 350km/h EMU train is one of the key parts for China high speed railways. Through analysis of the high speed bogy for CRH3 EMU train, the design conceptions and methodologies of the bogy structure and suspension systems are better understood. Technical procedures for the bogie design are carefully investigated, which includes

Optimization of high speed EMU suspension parameters for vibration reduction
Journal of Mechanical Science and Technology, 2013Various designs of high speed EMU (electric multiple units) operating at maximum speed of 400 km/h or above are under active development in many countries. Driving at such extreme high speed, the EMUs that are equipped with multiple power units and non articulated bogies normally experience severe level of vibration.

Reliability Distribution Law and Statistics Analysis for High-Speed EMU
Applied Mechanics and Materials, 2014The reliability design method is considered based on the EMU application in our country. It is verified that the vehicle reliability obeys the exponential distribution according to the statistical testing principles and practical data statistics of some high-speed EMU, in addition, the reliability after a period of time of operation, or to say, the ...

Analysis on reliability model of high-speed EMU bogie system
2013 International Conference on Quality, Reliability, Risk, Maintenance, and Safety Engineering (QR2MSE), 2013In this paper, fault tree analysis method and Bayesian network are introduced briefly. To overcome the restriction that fault tree analysis assumes the condition of an event as two-state, according to the mapping relationship between fault tree and Bayesian network, an event in fault tree is transformed to a node in Bayesian network, which will be ...

Effects of Crosswind to Running Safety of High-Speed EMU
International Conference on Transportation Engineering 2009, 2009The derailment accident of the train caused by the too big crosswind was often occurred in the world. It was a serious danger to the running safety of the railway train and the people's life and treasure. The highest running speed of the EMU has reached 350 km/h and the biggest wind speed nearly 30 m/h at the running area of the EMU, so running safety ...
