Abstract

Abstract This article proposes a solution to the problem of energy saving during life tests of plunger hydraulic cylinders. The author proposes a test stand using recovery. The purpose of the article is to disclose the device and the principle of operation of the hydromechanical system of the stand. Mathematical model of hydraulic drive of stand based on theory of volume stiffness is disclosed. Mathematical simulation results confirm and indicate the feasibility of recuperation in the test stand. In order to design a stand with the best energy indicators, it is proposed to carry out mathematical modeling of the hydromechanical drive of the stand, determine the numerical and structural parameters of the elements of the hydraulic system and mechanical transmission. The obtained theoretical results of mathematical modeling were applied and used in the design and manufacture of an experimental stand for resource tests of plunger hydraulic cylinders with energy recovery.
