Rybin A. Improvements for the bearing structure of a freight car through application of filler in its components

The research object is the processes of occurrence, perception and redistribution of loads in load-bearing constructions of freight wagons with fillers in their components. The study was conducted using modern methods of mathematical statistics, the Lagrangian II method of the genus, the finite element method, the Fisher method, the mathematical planning method of the experiment, modern methods of experimental research, methods for determining the project lifetime. As a result of the research, the urgent scientific task of improving the load-bearing structures of freight wagons by using fillers in their components has been solved, which will contribute to the improvement of railway operation. The results obtained can be used in the design and implementation of freight wagons.
