4. 2. Saving Energy in Construction Machinery using Displacement Control Hydraulics : Concept Realization and Validation

   Author : Kim Heybroek; Jan-Ove Palmberg; Jochen Pohl; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Strömningsmekanik;

   Abstract : In the sector of mobile hydraulics, valve controlled systems are predominant. In these systems the load force and speed are adjusted by control valves. In machines where multiple drives are used in parallel at extremely varying loads the energy efficiency of such systems is often compromised over large working regions. READ MORE
