Dynamic of an Axial Piston Pump With Floating Pistons

BATH/ASME 2024 Symposium on Fluid Power and Motion Control
Abstract A new structure of the axial piston pump was proposed to address the limitation of its application under low viscosity medium conditions due to the insufficient oil film bearing capacity. The piston of this structure is in a floating state in the axial direction, and both ends of the piston are supported by a discrete cylinder ...

Design and simulation of axial piston pump with constant flow

IEEE 10th International Conference on Industrial Informatics, 2012
There are flow pulsation in all existing piston pump, but this paper suggest a new constant flow method, and a axial piston pump with no flow pulsation in theory is designed. With the simulation in AMESim and MATLAB software, the dynamic characteristics of the new pump include pressure and flow are analyzed.

Study of a Novel Axial Piston Pump with Adjustable Tilting Piston

2019 IEEE 8th International Conference on Fluid Power and Mechatronics (FPM), 2019
In pump-control system, the flow rate is controlled by the rotating rate of pump or the displacement of the pump. The fixed displacement axial piston pump is designed for the rated operating condition. Therefore, the volumetric efficiency becomes worse when the rotating rate becomes lower.

Robust Design of Piston Assemblies in an Axial Piston Pump

International Journal of Fluid Power, 2014
The piston slipper in an axial piston pump demonstrates most complicated dynamic motions: two rotations (tilting toward to the swash plate and rotating about the pump shaft) and one translation together with the pumping piston. In addition, the slipper is used to lubricate the swash plate surface with hydraulic oil, but prevents high pressure fluid ...

Thermal modeling of axial piston pump and application

2015 International Conference on Fluid Power and Mechatronics (FPM), 2015
This paper analyses energy conversion and heat transfer in axial piston pump. According to it, the thermal mathematical model of axial piston pump is built by control volume method. This model can make full use of the dimension parameters of pump. The validity of the model is verified by the simulation for hydraulic system with axial piston pump.

The Shaft Torque of a Tandem Axial-Piston Pump

Journal of Dynamic Systems, Measurement, and Control, 2006
The objective of this study is to identify the best indexed position of two rotating groups within a tandem axial-piston pump for attenuating the torque ripple amplitude that is exerted on the shaft. By attenuating the torque ripple characteristics of the pump, other vibration aspects of the machine are also expected to be reduced.

The Effect of Oil Entrapment in an Axial Piston Pump

Journal of Dynamic Systems, Measurement, and Control, 1985
Values of pressure caused by entrapment beneath a valve plate have been calculated. The technique used consists of the solution of the dynamical equation of motion in the piston control volume. Instantaneous and average values of torque have also been deduced from the pressure distribution.

Analysis of the Run-in Behavior of Axial Piston Pumps

2018 Global Fluid Power Society PhD Symposium (GFPS), 2018
Axial piston pumps are universal displacement machines that are used in a vast variety of applications. Their high pressure resistance and ease of operation make them very popular, especially in mobile applications. Each pump is designed to last several thousand operating hours, but some fail before their expected time.
