Design, Modelling and Simulation of Electro-Hydraulic Self-Contained Cylinders based on Digital Hydraulics

2018

Master's thesis Mechatronics MAS500 - University of Agder 2018 Nowadays, hydraulic cylinders are mostly powered by a separate HPU and controlled by conventional servo and proportional valves. New trends have been under development the last years. The first trend is self-contained designs where the power unit is integrated in the cylinder design. Digital hydraulics is the second new trend where conventional flow control methods are replaced by simple ON/OFF valves and digital displacement pumps. A totally novel design would be a combination of the two mentioned trends. Designing a hydraulic cylinder that combines both the self-contained method and digital hydraulics is expected to results in…
