Nonlinear Model Predictive Control of Axial Piston Pumps

Journal of Dynamic Systems, Measurement, and Control, 2017
Variable displacement axial piston units are the core components of many hydrostatic and hydraulic hybrid drive trains. Therein, the fast and accurate control of the swash plate angle, utilizing the full possible dynamics of the displacement system, is essential for a good performance of the overall drive train.

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.

Predicting axial piston pump performance using neural networks

Mechanism and Machine Theory, 1999
Abstract A neural network model for an axial piston pump (bent-axis design) is derived in this paper. The model uses data obtained from an experimental setup. The purpose of this ongoing study is the reduction of the power loss at high pressures. However, at the beginning, a study is being done to predict the behavior of the current design of the ...

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 ...

Axial Piston Pump Slipper Balance With Multiple Lands

Fluid Power Systems and Technology, 2002
An explicit approach is developed which results in general flow and pressure drop equations for a multiple land slipper. A particular, and common, case of one balancing groove is considered allowing more accurate assessment of the pressure balance and probable slipper clearance. A comparison with the no-groove case is also made.

Power Loss of Slipper within Axial Piston Pump

Applied Mechanics and Materials, 2015
The pair between slipper and swash-plate is an important friction pair in the axial piston pump. Due to quick relative velocity, alternating load, numerous slippers, and high contact pressure between the friction surfaces, the wear-out and fatigue failure constantly occurs, which is one of the key factors affecting reliability of the piston pump. It is

Effects of Non-Uniform Pistons Distribution on Axial Piston Pump Flow Ripple

2019 IEEE 8th International Conference on Fluid Power and Mechatronics (FPM), 2019
The pressure ripple which causes vibration and noise of hydraulic systems are derived from the interaction of the high-frequency flow ripple of piston pumps and the resistance of hydraulic systems. Since an efficient method to reduce the vibration and noise can be started from the flow ripple of the piston pump.
