摘要

The present paper deals with hardware-in-the-loop (HIL) simulation of hydraulic components and systems. The main idea is to develop hydraulics by using a simulation model of it as a part of the machine. The interface between the real and simulated parts is defined by means of pressures and flows. The proposed idea makes it possible to test a variety of design parameters of a hydraulic system or single component on-line while running the practical experimental machine. The method is demonstrated in its application to a single-stage pressure relief valve in a simple hydraulic circuit. The real valve is replaced in the circuit by a HIL simulator mimicking the dynamic behavior of the valve. Finally the dynamic responses of original pressure relief valve and the HIL simulator are compared.
