Two-axle bogie design for electrical multiple unit. Part 2: Bogie frame fatigue test
International Journal of Materials and Product Technology, 1999The present article describes the bogie fatigue strength test. The bogie fatigue strength test was conducted on an unpainted bogie frame to verify compliance with the FEM analysis of bogie design. According to the bogie static strength test, we can compare the measured stress from the bogie fatigue strength test with the calculated stress values of the

Virtual Fatigue Experiment Analysis of Welded Bogie Frame
Applied Mechanics and Materials, 2012Fatigue failure easily occurs in the weld seam of bogie frame, fatigue life prediction is very important. Based on the UIC615-4 (Motive power units- Bogies and running gear-Bogie frame structure strength tests ) and IIW standard (Recommendations for fatigue design standard of welded joints and components-IIW document XIII-1965-03/ XV-1127-03), fatigue ...

Fatigue Life Prediction of a Railway Bogie Frame
Advanced Materials Research, 2008A 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 ...

Optimal Layout of Bogie Frames Considering Fatigue Strength
Volume 2: 24th Design Automation Conference, 1998Abstract Bogie frames are an important component within the entire system “train”. Currently, a layout of these frames with respect to durability is only carried out on the basis of substantially reduced load assumptions. By a more precise consideration of the states of operation an improved layout can be achieved with an optimal ...

Analysis on the fatigue cracks in the bogie frame
Engineering Failure Analysis, 2015Abstract 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 ...

Experimental and numerical simulation of bogie frame
2009Some 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.

Bogie Frame Fatigue Simulation Based on Flexible Multibody Dynamics
International Conference on Transportation Engineering 2009, 2009In this paper a non-linear multi-body model of a rail vehicle is combined with a finite element model of its bogie-frame. The finite element model is reduced by eigenmode representation. Simulation solution of the equation of motion is carried out using the combined flexible multi-body model. IV Track spectrum is used as input.

Process Integration of Fatigue Analysis for Welded Bogie Frames
Key Engineering Materials, 2006The automation of fatigue durability analysis for welded bogie frames according to the UIC-code is proposed by using the ModelCenter, which enables several tools used in fatigue durability analysis to be integrated, i.e. I-DEAS, ANSYS and BFAP, and an iterative analysis of geometrical changes in transom support bracket to be performed.

Engineering Approach to Weld Repairs for Bogie (Truck) Frames
2012 Joint Rail Conference, 2012As 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 ...
