Model predictive control design for axial-piston pump

IOP Conference Series: Earth and Environmental Science
Abstract The article presents model predictive control (MPC) design of the displacement volume control of a variable displacement axial-piston pump. The pump is intended for application in open loop circuit hydraulic drive system. The authors are developed a real-time control system contains two basic components: an electro-hydraulic ...

Experimental investigation in axial piston pumps barrel dynamics

, 2009
It is known that an axial piston pump barrel experiences small oscillations due to forces acting over it. Cavitation als o occurs in many cases, damaging the plate and barrel sliding surfaces and therefore reducing the volumetric and overall efficiency of the pump.

Rocketdyne LOX bearing tester program [PDF]

The cause, or causes, for the Space Shuttle Main Engine ball wear were unknown, however, several mechanisms were suspected. Two testers were designed and built for operation in liquid oxygen to empirically gain insight into the problems and iterate ...
