Strength and Modal Analysis of High Speed EMU Gearbox Housing

2019
With the continuous increase of China’s high-speed railway and the improvement of passenger vehicle dynamics and static performance requirements, the gearbox housing of the core component of power transmission is facing a severe test. Based on theoretical mechanics and finite element method, this paper calculates the static strength and modal state of ...

Flexible vibration analysis for car body of high-speed EMU

Journal of Mechanical Science and Technology, 2016
The 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

Experimental Modal Analysis of High-Speed EMU Carbody Structure

2012
Modal 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, 2012
The 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), 2013
In 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 ...
