Abstract
In order to increase the efficiency of railway transportation of strategic cargoes by railway transport, the design of a removable module is proposed, which allows adapting the body of an open-wagon to the transportation of Hessian equipment. The research is focused on the investigation of mechanical properties of a removable module concept. This module is proposed to be mounted on an open wagon and for transport of tracked vehicles and machines by it. The study of mechanical properties includes the strength analysis under its vertical load. The analyses are performed by means of the finite element method. At the same time, the Misses criterion was applied. It was established that the maximum equivalent stresses in the structure of the removable module concept are within the permissible limits. The conducted research will contribute to the improvement of the efficiency of railway transport operation, and it will be useful developments of the design of modern concepts of wagons' removable modules with a multifunctional purpose.
