Skliarevsky A. The increase of efficiency of hydraulic servo power drives of the test equipment.

Hydraulic servo power drive of the test equipment for mechanical load is the object of research. Increase of efficiency of hydraulic power drives of the test equipment is the goal of investigation. Creations of mathematical simulation theory of dynamic of hydraulic power drives, methods of automatic control theory, methods of synthesis of mechanisms are researching methods. Results and novelty. The problem of increase of efficiency of hydraulic servo power drives of the test equipment has been solved. Schemes and mathematical models of hydraulic power drives, which allow to prognosticate the accuracy and quantity of load of mechanical system, are proposed. Synthesis of hydrosystem for load of gas turbine engine disks is executed. Subject and introducing degree. Test complex for load of gas turbine engine disks are introduced in the factory "Motor - Sich", the results are used in text-books, which have permission of MES of Ukraine. Machine - contstruction is sphere of using.
