Suppression of abnormal chattering of a high-speed EMU carbody
Journal of Mechanical Science and Technology, 2021A carbody chattering phenomenon accompanied by bogie hunting movement was investigated. The online test results showed that the vehicle at a large tread conicity state exhibited insufficient stability when running at higher speeds, causing the hunting frequency of the bogie to continuously increase and approach the diamond-shaped deformation modal ...

High speed EMU modeling based on the measured data
2009 International Conference on Sustainable Power Generation and Supply, 2009Based on a large amount of actual measured data on railway line, this paper presents a modeling method using curve-fitting and probabilistic density functions for a high speed EMU. This method better simulates the real world and can be used to build a rapid data exchange between the trains and the traction power system simulation.
