A study on the optimum design for the valve plate of a swash plate-type oil hydraulic piston pump

Journal of Mechanical Science and Technology, 2015
Numerous studies have been conducted on hydraulic systems operating under high pressure. However, such systems are difficult to realize because of mechanical limitations as a result of tribological problems between relative sliding parts. Design techniques, manufacturing techniques, and tribological characteristics must be improved or innovated to ...

VIRTUAL PROTOTYPING OF AXIAL PISTON MACHINES OF SWASH PLATE TYPE

2019
Axial piston machines are widely used in the industry ranging from aerospace, agriculture, automotive, heavy machinery, etc. These applications require better pumps and motors to meet current market demands such as higher power density in hydraulic units, smarter pumps (diagnostics and prognostics), higher efficiencies, and compactness.

The Torque on the Input Shaft of an Axial-Piston Swash-Plate Type Hydrostatic Pump

Journal of Dynamic Systems, Measurement, and Control, 1998
Traditionally, the theoretical torque on the input shaft of a hydrostatic pump has been determined using a macroscopic “power-in, power-out” approach that neglects the time-varying aspects of this quantity and the compressibility of the hydraulic fluid within the circuit.

Tipping the Cylinder Block of an Axial-Piston Swash-Plate Type Hydrostatic Machine

Journal of Dynamic Systems, Measurement, and Control, 1997
Tipping the cylinder block within an axial-piston swash-plate type hydrostatic machine is a phenomenon that results in a momentary and sometimes permanent failure of the machine since the fluid communication between the cylinder block and the valve plate is instantaneously lost.

Slipper Tipping Within an Axial-Piston Swash-Plate Type Hydrostatic Pump

Fluid Power Systems and Technology, 1998
Abstract In this paper, the dynamic characteristics of the slipper are investigated analytically for the purposes of predicting the phenomenon of slipper tipping without the use of laboratory techniques. In particular it is shown that slipper tipping result from the reciprocating inertia of the piston / slipper assembly as well as the ...

Torque on the cylinder block of an axial-piston swash-plate type hydrostatic pump

2018
In this dissertation, both the ideal and non-ideal torque on the cylinder block of an axial-piston swash-plate type hydrostatic pump are examined. Traditionally, the torque on the cylinder block has been estimated by using a standard theoretical-expression that does not consider the compressibility of the fluid or the frictional characteristics within ...

The Discharge Flow Ripple of an Axial-Piston Swash-Plate Type Hydrostatic Pump

Journal of Dynamic Systems, Measurement, and Control, 1998
This research examines the idealized and actual flow-ripple of an axial-piston swash-plate type hydrostatic pump. For the idealized case, a “perfect” pump is examined in which the leakage is considered to be zero and the fluid is considered to be incompressible. Based upon these assumptions, closed-form expressions which describe the characteristics of
