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.

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.

Fatigue analysis of the cylinder in the axial piston pump

2015 International Conference on Fluid Power and Mechatronics (FPM), 2015
For the cylinder of the axial piston pump suffers complicated forces including hydraulic pressure force, mechanical forces and mutual coupling, which causes the cylinder fatigue damage with all forces whose fluctuation is caused by fluid striking on the cylinder of the pump cyclically, it is necessary to develop the fatigue analysis research.

Reduction of axial piston pump pressure ripple

Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 2000
The reduction in source flow ripple in hydraulic systems is the most effective method of reducing pump-generated pressure ripple and system noise. This paper describes reductions in axial-piston pump delivery flow ripple achieved using a novel timing mechanism which is inherently speed, flow and pressure sensing.

Dynamics Simulation Study of the Axial Piston Pump

Advanced Materials Research, 2013
Kinematics analysis based on the structure parameters of SCY14-1B type axial piston pump is taken in this paper, and the motion laws of the pistons relative to the cylinder block and the swash plate are got. A matlab simulation of the motion law is taken and the comparison between theoretical analysis and simulated results is very good.

Pressure Transients in an Axial Piston Hydraulic Pump

Proceedings of the Institution of Mechanical Engineers, 1974
A method is given for calculating pressure transients in an axial piston hydraulic pump. Some theoretical predictions are given of the effect of port timing and the effect of introducing restricting grooves at the ends of the kidney ports in the valve plate and suggestions are made of the effects of these parameters on noise emission; comparative ...

Improving the Volumetric Efficiency of the Axial Piston Pump

Journal of Mechanical Design, 2012
The volumetric efficiency is one of the most important aspects of system performance in the design of axial piston pumps. From the standpoint of engineering practices, the geometric complexities of the valve plate (VP) and its multiple interactions with pump dynamics pose difficult obstacles for optimization of the design.

The Analysis of Cavitation Problems in the Axial Piston Pump

Journal of Fluids Engineering, 2010
This paper discusses and analyzes the control volume of a piston bore constrained by the valve plate in axial piston pumps. The vacuum within the piston bore caused by the rise volume needs to be compensated by the flow; otherwise, the low pressure may cause the cavitations and aerations.
