“…A stand has been developed for resource testing of plunger hydraulic cylinders with energy recovery, in which one hydraulic cylinder performs the function of a hydraulic motor and acts on the second hydraulic cylinder, which performs the function of a hydraulic pump, through a transfer link in the form of a rocker arm. [17]. The influence of various design and functional parameters of the stand on the efficiency coefficient (Figure 7) has been studied.…”

The analysis of studies of the work processes of energy-saving hydraulic drives and devices was carried out in order to identify effective ways to reduce the dynamic loading and energy intensity of highly loaded technological machines and equipment. When studying the working processes of an energy-saving pneumohydraulic fifth wheel coupling of a timber tractor with a trailer, it was found that the recuperated power was 5.1-5.9 kW, and the average acceleration of the semi-trailer was 0.8 ... 0.81 m/s2. The energy-saving device of the Amkodor 208V front loader, which includes two torsion springs installed between the frame and the boom, reduces energy costs by 26%. The paper presents studies on energy saving during the operation of a hydraulic press with a pump-accumulator power supply. The results of studies of the energy-saving hydraulic drive of a forest manipulator and a chokerless skidding grip are presented. The energy-saving hydraulic drive of the manipulator column makes it possible to reduce the energy consumption of the column rotation by 25% and increase the productivity of the manipulator by 14%, and the chokerless grip hydraulic accumulator stores power in the range of 1.7 ... 2.1 kW. It is concluded that it is expedient to conduct further studies of the dynamics of energy-saving hydraulic drives of load-lifting mechanisms of manipulators of heavily loaded forestry vehicles.

One of the most important problems of modern mechanical engineering is the energy efficiency of technological equipment and manufactured products. A separate issue in this series is the technology and means of testing finished product samples, including hydraulic machines. In this article, an original scheme of a test bench for piston hydraulic cylinders and a method of mathematical modeling of the process of its functioning, based on the application of the theory of volumetric rigidity of hydraulic systems, is proposed, which makes it possible to describe with high accuracy and reliability the processes occurring in the test system during its operation. The test efficiency coefficient is proposed, which makes it possible to evaluate and compare various test processes by the criterion of their energy efficiency. An example of a preliminary calculation of the functioning of the proposed stand is given.
