Professor M. V. Vynokurov: stages of freight wagons creation (1930-1950)

The urgent task of modern historical science is the comprehensive study of the personalities of prominent scientists and engineers who made a significant contribution to the formation of science and technology. The article is devoted to the analysis of the activity of professor M. V. Vynokurov in the field of the creation of freight wagons. In the history of science and technology. M. V. Vynokurov pointed out that it had been decided to produce new wagons using light-alloy steel, which greatly reduced the weight of the dead load. Such a solution was based on the technical experience of the US wagon industry. Particular attention was paid to the unification of the parts and assemblies subjected to the process of wear and damage to the most, were replaced with the current and periodic repairs of the wagon. This important measure has significantly reduced the cost of manufacturing and was important for the organization of repair because it simplified the ability to replace worn parts with spare ones. M. V. Vynokurov is known as a prominent specialist in the field of rolling stock, he devoted his life to the development of carriages and rolling stock. In preparing this article, chronological, typological, comparative methods of historical knowledge, classification and systematization of historical sources and bibliographic material were used that allowed to systematize and critically evaluate the sources used in relation to the question of the stages of the creation of freight wagons. The role of professor M. V. Vynokurov in this process is shown, covering the 1930-1950 years, the most productive years of a scientist and engineer. It was established that due to the personal contribution of M. V. Vynokurov in the unification of parts for different types of freight wagons, there was a reduction in operating costs of railways. This was achieved due to the massive production of various types of freight wagons. Study of the development of freight wagons through the biography of the scientist-engineer M. V. Vynokurov, which is an integral part of the complex of knowledge, implies the application of a systematic approach as a methodological means of scientific knowledge.
