A stand for researching the dynamics and strength of a freight wagons bogie

Abstract

The purpose of the study is to characterize the laboratory equipment of a new generation that meets the requirements that are imposed today on the training of specialists in the rolling stock of railways. Analytical, diagnostic and didactic methods, theory and methodology of design and mechanics of freight wagon, theory of complex systems, systems engineering, modeling, as well as methodological tools for organizing experiments were used. The scientific novelty is the constructive and technological scheme of a specialized laboratory stand; a didactic set of materials for organizing laboratory work using this stand.It has been established that the introduction of a new rolling stock with an increased carrying capacity is the main trend of modern car building and should be accompanied by appropriate training of highly qualified specialists capable of further development of new generation freight wagons. It is noted that conducting educational and research sessions involves studying not only the problems of strength, but also acquiring skills in working with digital technologies for collecting and transmitting data. A detailed description is given of a specialized stand developed at the Department of "Wagons and Carriage Facilities" of PGUPS for studying the properties of dynamics and strength of freight wagons of the laboratory stand. In particular, the device of the base trolley model 18-9855 is shown, the technology of the stand operation is described, illustrative materials are given on the structure and principle of operation of the projected stand. For practical laboratory exercises, a typical version of laboratory work with the use of this stand is proposed. It is shown that the involvement of students in the implementation of practical experiments and applied bench research increases interest in the future profession and allows the formation of strong skills in practical diagnostics of the current state of a freight wagon.
