An Automation of Fatigue Durability Analysis for Welded Bogie Frame Using System Integration Techniques-Mechanical Engineering Projects


A web based automation of fatigue durability analysis for a welded bogie frame of railway vehicle is realized with several kinds of system integration techniques. The macro program of I-DEAS, the APDL of ANSYS, and an in-house fatigue code are utilized for the parametric geometry modeling and automatic generation of finite element models, the static stress analysis, the fatigue durability analysis, respectively. A multi-agent based engineering framework is implemented on the JADE to integrate the overall process. All engineering programs are integrated by a XML based wrapper. A database to contain engineering data and web based user interfaces are also developed. A parametric study is carried out to take into account the effect of geometrical change of transom support brackets on its fatigue durability. Developed automation techniques reduce remarkably the time and costs required in the fatigue durability analysis.


A bogie frame of railway vehicles plays an important role in sustaining the static load from the dead weight of a car body. Quasi-static loads occur periodically during curving and braking operations, and cyclic dynamic loads are caused by an irregular rail surface and relative movement of the attached equipment. Since the majority of the bogie frame is a welded structure which is very susceptible to the fatigue failure under such loads, a fatigue durability analysis to ensure the sufficient fatigue strength of its weldments is a relevant issue.

In practice, meanwhile, frequent geometric changes are required in early stages of the design process and the sharing of design parameters should be performed between sub tasks and in the overall process for the fatigue durability analysis. In spite of these necessities, these kinds of works can not be performed due to the lack of automation techniques for the required analysis.

In this paper, an automation of fatigue durability analysis for the weld bogie frame of railway vehicles is realized. The weld bogie frame is developed by the Korean Rotem Company, as shown in Fig.1

  1. Thanks , I have recently been searching for information approximately this subject for a while and yours is the best I’ve came upon till now. However, what about the conclusion? Are you positive in regards to the supply?|What i do not realize is if truth be told how you’re now not actually much more smartly-preferred than you might be now. You are so intelligent.
