The purpose of the study is to establish compliance of the design of the modernized car with the requirements for safe operation. An option has been proposed for upgrading a passenger wagon to a Mobile Diagnostic Complex for transporting a combined vehicle equipped with appropriate flaw detection equipment intended for rail diagnostics. The authors have established the most optimal option for locating the diagnostic vehicle on board the Mobile Diagnostic Complex (MDC) wagon, taking into account the additional load from the vehicle. To achieve this goal, the article developed a three-dimensional model of the supporting structure of the wagon body, proposed a methodology and presented the results of a study of the stress-strain state of the wagon body, taking into account the additional weight of the wagon. The article develops a methodology for studying the natural frequencies of vibrations of the wagon body and develops a three-dimensional model of the wagon for calculating dynamic indicators in the Universal Mechanism software package. Taking into account the previously carried out strength calculations, as well as in order to maintain the factory life cycle indicators of the supporting structure of the wagon body, it is recommended to use the model in the first version.

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.

“…Analysis of the literature [1][2][3][4][5][6][7][8][9][10][11][12] demonstrates that the issue of determination of the loads on the carrying structure of a flat wagon of circular pipes loaded with tank containers has not been studied yet. Therefore, it requires appropriate research in the field.…”

This research is concerned with the use of double walls filled with foam aluminum for an open wagon to decrease loading during operational modes. The research presents the strength calculation for the frame of a wagon with a consideration of the engineering solutions proposed. It was found that the maximum equivalent stresses appeared in the bottom section of the center sill behind the back support; they amounted to about 290 MPa and did not exceed the allowable values. The maximum displacements were in the middle parts of the main longitudinal beams of a section, and they amounted to 8.8 mm. The research also presents the strength calculation for a weld joint in the maximum loaded zones of the frame of a wagon and reports the results of the modal analysis of the frame of the improved wagon. It was found that the oscillation frequencies did not exceed the allowable values. The results of the research may be useful for those who are concerned about designing innovative rolling stock units and improving the operational efficiency of railway transport.
