Research on the Vibration Insulation of High-Speed Train Bogies in Mid and High Frequency
Shock and Vibration, 2018 According to a large amount of the test data, the mid and high frequency vibrations of high-speed bogies are very notable, especially in the 565~616 Hz range, which are just the passing frequencies corresponding to the 22nd to 24th polygonal wear of the ...

Reinforcement for Fatigue Fracture of Welded Bogie Frames
Journal of the Korean Society of Manufacturing Process Engineers, 2016 We consider the position and thickness of reinforcement with respect to fatigue fracture of welded bogie frames and propose an appropriate reinforcement method for many cases. The bogie frame is usually designed in accordance with JIS and KS, and operates under harsh load conditions: dynamic loads g...

Fatigue strength analysis of bogie frames under random loads [PDF]
Advances in Mechanical Engineering, 2019 In this study, a method for analyzing the fatigue strength of a bogie frame under a random load was proposed. Based on the geometric features, a welded joint coordinate system was established to compute the stress components of each node in this coordinate system.

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 7, Page 959-977, 10 March 2025.Abstract A novel damage detection model, which utilizes the spatiotemporal characteristics of the acceleration data, is proposed to assess the structural integrity of railway bridges. For this, the measured acceleration data are decomposed into several intrinsic mode functions (IMFs) using the sparse random mode decomposition model.
