# PROGRAM FOR AUTOMATION OF CALCULATIONS OF LOAD VALUES, ACTING ON A WAGON BODY AT ELECTRONIC CALCULATIONS WITH FURTHER THREE-DIMENSIONAL MODELING

Automation of the calculation of the loads acting on the body structure of a freight car during strength calculations is carried out with further three-dimensional modeling using information technology. A functional diagram of the developed program for calculating the loads acting on the car body is given. The stages of development and the basic modules of a software product that implements mathematical calculations are determined. The features of the software implementation of the presented algorithms using the object-oriented programming language C# are discussed. The developed program in C # language with the use of the integrated Visual Studio environment allows to increase the accuracy and reduce the time for calculating the loads acting on the body of a freight car during strength calculations with various initial technical and economic characteristics and design features of freight cars. An engineering analysis using load values obtained using the developed program is presented.
