ANALYSIS OF DESIGNS, MODELS AND METHODS OF STUDYING THE DYNAMICS OF HIGH-ROTATION ELEMENTS OF TANK ENGINES (REVIEW ARTICLE)

A lot of problems arise when tank engines are equipped with high-speed elements. They are related to the need of analyzing the stress-strain state and critical modes of rotation of these elements. For that reason, it requires an in-depth analysis of requirements and constructive solutions of engines and their high-speed elements. Moreover, modern studies of engine dynamics attract attention. Attention should also be paid to the analysis of existing designs of turbocharging systems of tank engines. It is important to analyze the models and research methods of the static and dynamic stress-strain state of turbocharger impellers as well. The analysis of problem aspects has been carried out and it is possible to note that for now the problem of studying the stress-strain state and critical modes of rotation of high-speed elements of tanks and engines for armored vehicles does not have a complete solution. We need new approaches, models and research methods and tools that create a basis for substantiating progressive technical solutions.
