Analysis on Load Spectrum of Bogie Frame for High-Speed EMU
Applied Mechanics and Materials, 2014The load spectrum, on which there is not a thorough research, is the key factor of the safe operation of EMU. A dynamic model of some high-speed EMU is established and the load time history of main load on frame is obtained through simulation and analysis based on the Beijing-Tianjin route.

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.

Experimental Modal Analysis of High-Speed EMU Carbody Structure
2012Modal is the natural characteristic of structural vibration, each mode has a specific frequencies, damping and modal shape. Modal parameters reflect the dynamic properties of the structure. The dynamic characteristics of car-body structure play an important role to the stability and comfort of the High-speed EMU (Electric Multiple Unit).

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

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 ...

Flexible vibration analysis for car body of high-speed EMU
Journal of Mechanical Science and Technology, 2016The resonance of the flexible vibration of car body, which has not been detected before on a passenger coach, occurred recently on a high-speed Electric multi units (EMU) when the train was running at 300 km/h on Beijing-Shanghai line. In this investigation, the force transmission from track to car body via suspensions is elaborated first with possibly
