Justification of a Rational Design of the Pivot Center of the Open-top Wagon Frame by means of Computer Simulation

The study of the strength and fatigue life of a welded load-bearing structure of the open-top wagon body was carried out by methods of mathematical simulation. The causes of occurrence of crack-like defects in the pivot center of the wagon were detected. Options to improve the load-bearing structure of the pivot center of newly manufactured open-top wagons and repaired wagons with defects were proposed. For the modified design of the open-top wagon pivot center conception complex calculations were made that confirmed its efficiency.
