Special Issue Information

Dear Colleagues,

I would like to bring to your attention this Special Issue on "Fluid Power Components and Systems". Essentially, fluid power is the transmission of forces and motions using a confined and pressurized fluid with its main overall merit of density power. Occasionally, fluid power could be considered the 'dark matter' of power transmission systems: it is there, but it is not 'directly' observed. Over the years, numerous investigations and great researchers have established fluid power fundamentals, in both components and systems.

This Special Issue on "Fluid Power Components and Systems" aims to disseminate recent advances of fluid power technology, contributing to the existing literature. The scope of this Special Issue focuses on a wide range of topics, including the following:

  • New methodologies for the analysis, modeling, simulation, and design of hydraulic and pneumatic components
  • Advanced configurations and design for hydrostatic pumps and motors
  • New configurations and design solutions for hydraulic valves and actuators
  • New experimental approaches and techniques in hydraulic and pneumatic components
  • Component sizing and manufacturing techniques in fluid power components
  • Fluid power production methods
  • New materials in fluid power components
  • Advanced system configuration in mobile and industrial fluid power
  • Applications of fluid power in the field of hydrostatic, hybrid, and power split transmissions
  • Efficiency labeling in fluid power components
  • Energy rating in fluid power systems
  • Monitoring, fault detection, and life reliability in fluid power components
  • Design by end-user: diagnosis, prognostic, and energy consumption evaluation
  • Biodraulics: fluid power in bioengineering
  • Hydraulic drives and actuators in powered prosthetics
  • Noise and vibration in hydraulic components and systems
  • Tailor-made fluid power technology
  • Environmental topics and issues in fluid power

The purpose of this Special Issue is to gather together the cutting-edge approaches and results in the fluid power field in its wide spectrum.

On behalf of the journal, I invite you to consider this Special Issue as an opportunity and an optimal launch pad to publish and disseminate your research approaches and results in the captivating fluid power field.

We are looking forward to receiving your submissions.

This article presents a methodology for predicting the fluid dynamic behavior of a gear pump over its operating range. Complete pump parameterization was carried out through standard tests, and these parameters were used to create a bond graph model to simulate the behavior of the unit. This model was experimentally validated under working conditions in field tests. To carry this out, the pump was used to drive the auxiliary movements of a drilling machine, and the experimental data were compared with a simulation of the volumetric behavior under the same conditions. This paper aims to describe a method for characterizing any hydrostatic pump as a “black box” model predicting its behavior in any operating condition. The novelty of this method is based on the correspondence between the variation of the parameters and the internal changes of the unit when working in real conditions, that is, outside a test bench.

This paper reports work performed to support the development of condition monitoring strategies through extensive use of simulation. The aim is to define and implement a methodology that makes the development of lumped-parameter models more efficient and straightforward. This is achieved by considering the model architecting and the approach adopted for fault injection early in the process. Various options are proposed and compared for both these activities. The Bond-Graph formalism is extensively used for its ability to focus on the model structure and interfaces, the nature of the phenomena considered, and potential causality issues. The interest of the proposed methodology is illustrated with the example of a pressure-compensated axial piston pump that supplies the flight control actuators in helicopters. The pump model architecting and the fault injection are presented, with special attention to jamming and erosion of the pump compensator valve. From these examples, it is shown that the proposed methodologies provide an efficient model-based means of identifying fault signatures and implementing low-cost condition monitoring features in an industrial context.

The internal cushioning systems of hydraulic linear actuators avoid mechanical shocks at the end of their stroke. The design where the piston with perimeter grooves regulates the flow by standing in front of the outlet port has been investigated. First, a bond graph dynamic model has been developed, including the flow throughout the internal cushion design, characterized in detail by computational fluid-dynamic simulation. Following this, the radial movement of the piston and the fluid-dynamic coefficients, experimentally validated, are integrated into the dynamic model. The registered radial movement is in coherence with the significant drag force estimated in the CFD simulation, generated by the flow through the grooves, where the laminar flow regime predominates. Ultimately, the model aims to predict the behavior of the cushioning during the movement of the arm of an excavator. The analytical model developed predicts the performance of the cushioning system, in coherence with empirical results. There is an optimal behavior, highly influenced by the mechanical stress conditions of the system, subject to a compromise between an increasing section of the grooves and an optimization of the radial gap.
