Determination of load-carrying capacity of tank wagon with a loaded-friction spine girder

Abstract

was found that the maximum vertical acceleration, which acts in the center of mass of the load-carrying structure of the tank-car in the empty state is about 1.72 m/s 2 (0,17g), which is about 20% lower than the acceleration of the standard structure. The main indicators of the strength of the load-bearing structure of the tank wagon were calculated. The method of joined elements, which is implemented in the SolidWorks Simulation (CosmosWorks) program complex, was used herewith. As lumped elements, we used spacious isoparametric tetrahedrons. The calculation was performed in quasi-statistics. It was found that the maximum equivalent loads occur in the area of the manhole placement are 173.7 MPa, which is 13% lower than in the standard structure. The conducted research will contribute to the creation of guidelines for the design of innovative structures of rail transport vehicles with improved technical and economic characteristics, as well as to increase the efficiency of the operation of rail transport.
