Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
In this paper, the fracture problems appearing in operation and the reasons of the welded bogie frames of railway vehicles were explained firstly, and the current design situation of fatigue life and reliability of bogie frame were summarized. The railway vehicle design standard, which plays a decisive role in the bogie frame design, was analyzed. The traditional determining value method by using safety coefficient to ensure sufficient strength should be replaced by the probabilistic reliability method. The fatigue life initiative reliability design for the welded bogie frame was studied, and the implementation means and steps were given. Finally, some difficulties of utilizing the method of fatigue life initiative reliability to design welded bogie frame were put forward.
