Abstract

To enhance the working performance of the axial piston motor, computational fluid dynamics (CFD) software was employed to investigate the flow field characteristics of the axial piston motor. This paper presents a new type of damping groove and conducted three-dimensional computational fluid dynamics transient simulations on the unequal and new damping groove designs of the distribution plate. Pressure, flow rate fluctuation, and cavitation phenomena were measured under various structural parameters to verify the simulation results. The experimental results indicate that a well-designed distribution plate can not only reduce the pressure fluctuation of the motor but also enhance its anti-cavitation performance. Additionally, appropriately adjusting the structural parameters of the damping groove can effectively suppress the cavitation phenomenon to a certain extent. This can efficiently reduce the noise and vibration caused by cavitation, thereby significantly improving the reliability and lifespan of the axial piston motor.

基于 CFD 的轴向活塞发动机流场特性分析与优化

为了提高轴向活塞发动机的工作性能，采用计算流体动力学（CFD）软件研究了轴向活塞发动机的流场特性。本文提出了一种新型阻尼槽，并对不等阻尼槽和新型阻尼槽设计的配流板进行了三维计算流体动力学瞬态模拟。在不同结构参数下测量了压力、流速波动和气蚀现象，以验证模拟结果。实验结果表明，设计合理的配流板不仅能降低电机的压力波动，还能增强其抗气蚀性能。此外，适当调整阻尼槽的结构参数也能在一定程度上有效抑制气蚀现象。这可以有效降低气蚀引起的噪音和振动，从而显著提高轴向活塞电机的可靠性和使用寿命。

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.
