Modeling and Simulation on Light Axial Piston Pump

Applied Mechanics and Materials, 2010
Flow and pressure regulation axial piston pump is studied in this paper. Model of the pump is built in AMESIm, and then characteristics of flow rate and pressure are calculated and analyzed in this model. This provides a good platform to the design and research of axial piston pump.

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 ...

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 ...

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.

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.

Analysis of KZB axial piston pump's self-cooling

2010 5th IEEE Conference on Industrial Electronics and Applications, 2010
This paper presents a totally new kind of pump, called KZB pump, which has highly efficiency in self-cooling. Compared with other type of pumps, it has a great advance in self-cooling. The conclusions have been proved by several industrial experimental results. KZB pump, made according to the principles of double-end with oil axial piston pump, and its

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 ...
