Abstract

Life service forecast of the hopper car body welded load-bearing structure of the design loading in operation is made on the basis of mathematical modeling. The elastic properties of the car body are taken into account when modeling the load alongside the longitudinal forces appearing in the process of car’s movement when a part of the train or shunting is specified. The problem is solved in a dynamic formulation by using hybrid dynamic models of cars movement in conditions of real railway track irregularities and detailed plate finite element models. The fatigue life of the most loaded load-bearing structures of the hopper car was assessed within the framework of the determined Serensen-Kagayev model of multicycle fatigue, which is the basis of the normative calculation. In assessing the durability of the welded load-bearing structure of the body, using the updated methodology, the authors evaluated the influence of stress concentration in the area of welded joints.
