To the question of modeling of railway tank shell failure by safeguard bow impact at overswinging

Abstract

The paper presents a method for calculation of railway tank shells at an impact with the consideration for material plasticity. The authors have modelled failures of a tank shell with a safeguard bow on a bracket and without a bracket in a non-linear static formulation. Modeling allows formulating a methodology for determination of strength properties of railway tank shells in conditions of an impact and allows realizing protection of tender spots of design. It is determined that the use of the safeguard bow on a bracket is a preferred technical solution, that is why this design is selected for the study aimed at gaining the best parameters of tank shells.
