A hydraulic system of a flexible bar vibration test bench

Abstract

The invention relates to a hydraulic system of a flexible rod vibration test bench. The system comprises a power source hydraulic system, a stretch hydraulic system, two push hydraulic systems and a twist hydraulic system, wherein the power source hydraulic system is simultaneously connected with the stretch hydraulic system, the two push hydraulic systems and the twist hydraulic system; the stretch hydraulic system is connected with a stretch load device of the test bench; one of the push hydraulic systems is connected with a front-back swing load device of the test bench, and the other push hydraulic system is connected with a left-right swing load device of the test bench; the twist hydraulic system is connected with a twist load device of the test bench. The stretch hydraulic system, the two push hydraulic systems and the twist hydraulic system are driven respectively through the power source hydraulic system to work independently, push, pull and twist functions of a test object are realized, and higher control precision is achieved through electro-hydraulic combined control. Meanwhile overload can be very easily prevented, and the safety coefficient is high.

Description

technical field [0001] The invention relates to a hydraulic system of a vibration test bench for flexible rods, in particular to a hydraulic system capable of realizing the functions of pushing, pulling and torsion for an experimental object on the test bench. Background technique [0002] Nowadays, many universities, companies and factories have various projects, and many projects are often based on experiments. Experimental equipment to achieve related functions. Many experimental devices often only have one function. To realize the corresponding function, it is necessary to operate back and forth on multiple devices, which is very cumbersome, and it is not possible to complete multiple action requirements at the same time. The hydraulic system of the flexible rod vibration test bench makes up for the above-mentioned defects, not only meeting the requirements of the force, but also performing several actions at the same time. Through the control of electro-hydraulic comb...
