Abstract

Addressing the challenges in accurately predicting the frequency response and flow output of high-speed on/off valves (HSVs) in digital hydraulic systems, this study investigates their dynamic response and output characteristics through integrated electromechanical-hydraulic co-simulation and experimental testing. A dynamic model of the HSV, including its load, is established. An analysis method for dynamic performance, based on the load force function, is proposed to examine the valve's opening and closing behavior and the resulting flow characteristics. Structural parameters are subsequently optimized. Results show that the optimized valve exhibits significantly reduced opening and closing times, and its cutoff frequency increases from 37 Hz to 53 Hz. Additionally, it is found that an increase in operating frequency narrows the linear flow modulation range and reduces output flow, while a decrease in pressure differential leads to a parabolic decay in output. Experimental results validate the simulation, demonstrating that the prototype achieves a linear modulation range of 30 %–70 % at 40 Hz and a maximum operating frequency of 60 Hz. This research establishes an integrated electromagnetic-mechanical-hydraulic load force model and proposes a structural optimization framework based on load force characterization. This provides a new co-design approach for the synergistic optimization and precise control of HSVs.

基于结构优化和负载力表征的高速开关阀动态响应及输出特性

针对数字液压系统中高速开关阀（hsv）的频率响应和流量输出难以准确预测的问题，通过机电液联合仿真和实验测试，研究了高速开关阀的动态响应和输出特性。建立了包括载荷在内的HSV的动力学模型。提出了一种基于载荷力函数的动态性能分析方法，分析了阀门的启闭特性及其产生的流量特性。随后对结构参数进行了优化。结果表明，优化后的阀门开启和关闭次数显著减少，截止频率从37 Hz提高到53 Hz。此外，发现工作频率的增加缩小了线性流量调制范围并减小了输出流量，而压差的减小导致输出呈抛物线衰减。实验结果验证了仿真结果，表明样机在40 Hz时实现了30% - 70%的线性调制范围，最大工作频率为60 Hz。建立了电磁-机械-液压综合载荷力模型，提出了基于载荷力表征的结构优化框架。这为hsv的协同优化和精确控制提供了一种新的协同设计方法。

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.
