This article describes the results of computer modeling of temperature resistance of the hopper car load-bearing structure. For this purpose, a spacious model of load-bearing structure of an opera-car in SolidWorks program complex was created. As a prototype the hopper car model 20-9749 was used, which was built by "Ukrspetsvagon" and is intended for transportation of pellets and hot sinter. Calculation of the strength of the load-bearing structure of the operating car was carried out by the method of concatenated elements, which is implemented in the program complex CosmosWorks. When creating the design scheme, the temperature impact of the transported cargo on the inner surface of the hopper body was taken into account. The results of the calculation showed that the maximum equivalent loads in the load-bearing structure of the hopper car is about 340 MPa and is located in the area of interaction between the backbone beam with the kingpin. The maximum load in the load-bearing structure of the opera-car, which is caused by temperature pressure, occurs in the vertical struts and hump and amounts to 335 MPa, which is 3% lower than the load of the plinth of the material of the structure. The influence of temperature load on the indicators of load-bearing capacity of opera-car structure has been determined. It was found that this dependence is linear. The maximum equivalent loads at a temperature of transported cargo at 700°C are more or less equal to the plinth of the material of the structure. With a slight increase in the temperature impact on the supporting structure of its strength indicators will not be ensured. Therefore, there is a need to improve the load-bearing structure of the opera car to ensure its durability in operation. The conducted research will contribute to the creation of guidelines for the design of modern designs of freight cars with improved technical and economical indicators
