The article describes the design of the experimental installation that provides new data on cavitation-erosion failures in high-temperature cooling systems. Based on the analysis of domestic and foreign sources of scientific and technical information concerning the research of cavitation processes, technical objects where cavitation processes take place, factors that affect the intensity of cavitation-corrosion destruction, and methods that are used for cavitation research are identified. A modernized design of the laboratory unit is proposed. The main element of it is a high-frequency magnetostrictive vibrator. Due to the sealed experimental cavity, the unit allows the determining of the intensity of cavitation-erosion destruction at high liquid temperatures and pressure above atmospheric, which is typical for high-temperature cooling of marine diesels. The usage of the installation will allow getting the correct data about the resource of elements of high-temperature cooling systems for marine diesels.

“…Использование компьютерных технологий позволяет не только существенно сократить сроки создания нового двигателя, но и провести многовариантный анализ конструкции. Особая актуальность сокращения сроков проектирования и подготовки производства новых и модернизированных двигателей обусловлена ситуацией, сложившейся в отечественном двигателестроении, и острой необходимостью создания отечественных конкурентоспособных двигателей внутреннего сгорания (ДВС) [3]. Корректность результатов кинематического и динамического анализа КШМ ДВС является обязательным условием достоверности прочностных расчетов деталей.…”

The required level of reliability of modern forced engines can be provided only on condition of their high-quality design, which is based on the strong calculation of the most loaded parts, which include parts crank mechanism. The article shows the importance of kinematic and dynamic analysis of crank mechanism in the process of designing an internal combustion engine and their role in ensuring the reliability of the engine, describes ways to solve the problem of kinematic and dynamic analysis of crank mechanism. The comparative analysis of static and dynamic models of crank-crank mechanisms is given. Calculation schemes, the sequence of kinematic and dynamic analysis of the mechanism, the system of equations, allowing to determine the forces acting in the crank mechanism, are presented. On the basis of the vector diagrams of loads on the crankshaft connecting rod presented in the article the expediency of application of dynamic models of crank mechanisms with SIM-metric and asymmetric connecting rods for analytical calculations of piston engines is proved. The results of analytical calculations of the dynamics of crank mechanism of four-stroke diesel supercharged size 13/14 are presented. It is shown that with the modern development of computer technology and software, the complexity of such calculations practically does not increase, and the results are close to those obtained by numerical analysis of dynamics using three-dimensional solid-state models. Recommendations on the use of "light" software products Ltd, which allows to perform kinematic and dynamic analysis of mechanisms in the educational Pro-process and solution design tasks. The results presented in the article prove the appropriateness of using the coordinate method to determine the kinematic parameters of the third replacement weight of the connecting rod and the ability to ensure the required accuracy of the calculations performed on the basis of the analysis of rod systems.

The implementation of federal programs for the modernization of the transport system of the Russian Federation requires the solution of a set of tasks, the most important of which is the training of highly qualified specialists in the transport industry. A necessary condition for high-quality training of specialists is certainly a modern educational and laboratory base. The Admiral Makarov State University of Maritime and Inland Shipping has been training specialists in the field of marine energy for many decades. In order to continue training specialists in this area at a high level, it is necessary to modernize the material base, create laboratories that meet modern requirements. In order to achieve this goal, a project to create an educational and scientific center “Energy efficiency and reliability of marine machinery and mechanisms” is proposed. The concept of creating a center is presented in the paper, the laboratories that should be part of it are listed, the examples of laboratory layouts and their main equipment are provided. It is proposed to include a laboratory for testing engines in container design and a floating laboratory in the educational and scientific center. The creation of an educational and scientific center equipped with modern equipment will provide conditions for high-quality training of specialists for industry enterprises, as well as provide an opportunity to solve current scientific problems in the field of marine energy. The concept of creating an educational and scientific center is supported by the Board of Trustees of the University
