An original design of the stand is proposed for carrying out resource tests of plunger hydraulic cylinders with energy recovery. The stand is designed for life tests of high and medium power plunger hydraulic cylinders, which allows saving up to 80% of energy due to its reuse during testing. In the article, based on the use of the theory of volumetric stiffness of hydraulic systems, a mathematical model of the hydro mechanical system of the stand is obtained, which allows to describe with high accuracy the functioning of the stand in the process of testing hydraulic cylinders. Studies of the functioning of the proposed stand, carried out using the obtained mathematical model, have confirmed the high efficiency of the energy recovery method used in the development of the stand's schematic diagram. The solution of the mathematical model was carried out using the SimInNech software package for solving differential equations. The analysis of the results obtained in the calculation of the results allows already at the design stage of the stand to reveal the rational values of its design parameters, which will give a significant saving of resources during its operation. |
