Abstract
As an important control component in hydraulic system, the static and dynamic performance of electro-hydraulic proportional valve directly affects the performance of the whole control system. In this paper, through the analysis of the operating principle of a specific pilot-operated proportional reducing valve, two static and dynamic mathematical models are established to simulate the performance of the valve. One model is constructed by empirical formulas, while the other one is corrected through CFD simulation and proportional solenoid test, firstly, a series of flow and fluid force interpolation models are obtained through CFD simulation, replacing the original empirical formulas. Secondly, relevant parameters of the proportional solenoid are corrected by testing its static and dynamic characteristics. To validate the validity of model correction and the accuracy of the corrected model, the static and dynamic experiments of the valve were conducted, and the results are compared with the simulation results of the models, which show that the experimental results are in better agreement with the simulation results of the corrected model. Therefore, this model can be used for further research on the valve.
期刊介绍：
Flow Measurement and Instrumentation is dedicated to disseminating the latest research results on all aspects of flow measurement, in both closed conduits and open channels. The design of flow measurement systems involves a wide variety of multidisciplinary activities including modelling the flow sensor, the fluid flow and the sensor/fluid interactions through the use of computation techniques; the development of advanced transducer systems and their associated signal processing and the laboratory and field assessment of the overall system under ideal and disturbed conditions.
FMI is the essential forum for critical information exchange, and contributions are particularly encouraged in the following areas of interest:
Modelling: the application of mathematical and computational modelling to the interaction of fluid dynamics with flowmeters, including flowmeter behaviour, improved flowmeter design and installation problems. Application of CAD/CAE techniques to flowmeter modelling are eligible.
Design and development: the detailed design of the flowmeter head and/or signal processing aspects of novel flowmeters. Emphasis is given to papers identifying new sensor configurations, multisensor flow measurement systems, non-intrusive flow metering techniques and the application of microelectronic techniques in smart or intelligent systems.
Calibration techniques: including descriptions of new or existing calibration facilities and techniques, calibration data from different flowmeter types, and calibration intercomparison data from different laboratories.
Installation effect data: dealing with the effects of non-ideal flow conditions on flowmeters. Papers combining a theoretical understanding of flowmeter behaviour with experimental work are particularly welcome.
