Abstract

This article presents the features and results of the study on the integration of circular pipes in the supporting system of boxcar on the basis of the method proposed by the author. Application of this method ensures minimal consumption of materials under the conditions of strength and operational reliability by ensuring rational indicators of strength. Results of complex theoretical and computational checks of durability and operational reliability of improved boxcar design by the computer modeling pointed to the efficiency and effectiveness of the implemented technical solutions. So as a result of its test of strength in all cases calculated according to calculation mode found that the resulting equivalent load does not exceed the allowable normalized values, fatigue strength (in a test in 107 cycles) is provided, project service life is more than 32 years. Moreover, the results of additional analysis to ensure strength in welded joints have also confirmed their performance.
