Loading on the carrying structure of a flat wagon when transporting firing military equipment

Abstract

The study deals with research through mathematic modeling of the dynamic loading on the carrying structure of a flat wagon in transportation of military equipment conducting fire. A 13-401 flat wagon loaded with a tank with combat load of 55 tons was taken as the prototype. The mathematical model was solved in MathCad software. It was established that the maximum acceleration on the carrying structure of a flat wagon in the horizontal plane was about 40 m/sec2 , and in the vertical plane – about 10 m/sec2 . The values obtained were considered in strength calculation for a flat wagon. The calculation was made using the finite element method in CosmosWorks software. It was established that the maximum equivalent stresses in the carrying structure of a flat wagon exceeded the admissible values twice. The results of the study will encourage engineers to design carrying structures of flat wagons intended for transporting military equipment firing in motion.
