A Study on the Characteristics of Bogie Frame Materials

Applied Mechanics and Materials, 2013
This paper describes the structural analysis, load tests and combined stress of the bogie frame. It seeks to identify the structural safety of the bogie frame when the bogie is assembled on the train and a train service is implemented. The bogie consists of the bogie frame, suspension, wheels, brakes and transmission, etc.

A Study on the Structural Analysis and Loading Test of the Bogie Frame

Key Engineering Materials, 2006
This paper describes the results of structural analysis and loading test of a bogie frame. The purpose of the analysis and test is to evaluate the safety and functionality of the bogie frame under maximum load. The bogie system consist of the bogie frame, suspensions, wheel-sets, a brake system and a transmission system.

Analysis on the fatigue cracks in the bogie frame

Engineering Failure Analysis, 2015
Abstract Aiming at the problem that some fatigue cracks occurred in the bogie frame of B-type metro vehicles and based on the actual stress and acceleration time history, it is found through the comparison between time and frequency domains that the main reason resulting in the fatigue cracks is that the low-frequency wheel–rail impact due to rail ...

Suppression of the flexible carbody resonance due to bogie instability by using a DVA suspended on the bogie frame

Vehicle System Dynamics, 2021
A novel method is proposed to suppress the flexible carbody resonance due to bogie instability by hanging a dynamic vibration absorber (DVA) to the bogie frame.

Fatigue Life Prediction of a Railway Bogie Frame

Advanced Materials Research, 2008
A fatigue life prediction method was introduced. The method was based on the combination of time domain and frequency domain method. Dynamic model of a complete railway locomotive system was established using SIMPACK software. The dynamic load histories acting on the bogie frame can be obtained by the Multi-Body System (MBS) analysis technique with ...

An investigation into the fatigue failure of metro vehicle bogie frame

Engineering Failure Analysis, 2020
Abstract Metro vehicle bogie frame is usually subjected to complex external excitations. The fatigue damage accumulation of bogie frame is induced by multiple elements and may even lead to failure hazard. Therefore, a comprehensive investigation into the influencing elements was conducted in this paper.

Engineering Approach to Weld Repairs for Bogie (Truck) Frames

2012 Joint Rail Conference, 2012
As welded rail car truck (bogie) frames become more common than cast frames and as they accumulate more service time and mileage, increasing numbers of service-induced defects are bound to occur. Some items requiring repair or rehabilitation include cracks, accident damage, excessively worn surfaces, and modifications for addition of equipment or ...

Experimental and numerical simulation of bogie frame

2009
Some experiences on numerical calculation and experimental data analysis from full-scale tests are shown in this paper, with the focus on the benefits that came from an a priori estimation of sensible zones of bogie frames for each loading condition.
