Abstract

Alternative method of calculation of the projected design of the tank car for strength and service life is considered. To improve the reliability of calculations, the results of the strength determination solution are carried out for different levels of discretization of the studied object and compared with the available analytical solutions. The resource of the structure is defined for one of the most loaded units of the welded joint. The estimation of resource indicators is carried out on the basis of experimental data on the fatigue limit of welded joints, taking into account the geometry of the node and the method of loading. In this case it is possible to avoid unreasonably high forecasts of durability of products. The prediction is improved by taking into account the rate of cyclic degradation of the material on the basis of original experiments on the degeneration of the static deformation diagram with increasing operating time. The paper presents the results of a numerical experiment to determine the durability of the tank structure at different rates of degradation of the material properties. Simulation of a random process of tensioning changes at a dangerous point of the structure was performed using randomization operation.
