Problems solved by technology

Therefore, it is particularly important to design a hydraulic cylinder test equipment for the fatigue performance and external load characteristics of the hydraulic cylinder. The traditional fatigue performance and external load characteristics are only determined by theoretical calculations, which is not practical. Once the calculation is wrong, the The consequences are extremely serious

Abstract

The invention relates to the technical field of hydraulic cylinder testing, in particular to a hydraulic cylinder testing device. It includes: a test bench, a fixing system, a driving system, a measuring system and a control system; the hydraulic cylinder testing device provided by the present invention has high efficiency in measurement and high reliability, and the block design makes the measurement more targeted and at the same time adjustable The space makes the test object unrestricted and suitable for testing large hydraulic cylinders. In addition, the invention has simple structure, light and convenient components, and breaks through the characteristics of low alignment of traditional test benches and high testing costs caused by special test benches.

Description

technical field [0001] The invention relates to the technical field of hydraulic cylinder testing, in particular to a hydraulic cylinder testing device. Background technique [0002] Hydraulic cylinder is an important energy conversion device, which has simple structure, simple working principle, reliable operation and relatively large driving force, so it is widely used in industry. Since hydraulic cylinders are mainly used in areas with large loads, and the requirements for various performances such as control accuracy are high, the performance of hydraulic cylinders directly determines the accuracy and safety of the transmission system. Therefore, it is particularly important to design a hydraulic cylinder test equipment for the fatigue performance and external load characteristics of the hydraulic cylinder. The traditional fatigue performance and external load characteristics are only determined by theoretical calculations, which is not practical. Once the calculation is...
