Measurement of Slipper Behavior in Swashplate-Type Axial Piston Pumps
Tribology OnlineIn swash plate type axial piston pumps, slipper/swash plate sliding surfaces is subject to high fluctuating load. Therefore, the slippers are required to provide stable operation and reduce losses due to sliding. The behavior of the slipper fluctuates in

Assessment and preliminary design of an energy buffer for regenerative braking in electric vehicles [PDF]
Energy buffer systems, capable of storing the vehicle energy during braking and reusing this stored energy during acceleration, were examined. Some of these buffer systems when incorporated in an electric vehicle would result in an improvement in the ...

Axial piston pumps, new trends and development
, 2012 International audience ; Efficiency improvement is a key issue in any machine. The fluid power industry relies on volumetric pumps which need to pump high pressure fluid to a set of actuators located at different positions in a given device; the higher the pressure, the smaller the actuators need to be, therefore allowing to reduce the weight of the ...

Considerations for the Design of Sinusoidal Slug Testing Methods
Groundwater, EarlyView.Periodic hydraulic tests estimate aquifer properties using controlled groundwater‐level oscillations. Evaluating two sinusoidal slug‐test designs shows large motion errors when transfer‐link and flywheel ratios are high or variable. Rotating‐drive mechanisms are therefore suboptimal; stepper‐motor winches generate more accurate sinusoidal motion ...
