Abstract [en]

Today's high oil prices and more stringent environmental requirements have led to that manufacturers of mobile construction equipment try to make their products more energy efficient. With this in mind a project about hybridization of hydraulic systems has been formed. The purpose of this project was to analyze the savings that can be achieved by hybridization of hydraulic systems. A reach stacker truck (Kalmar DRD450-80S4XS) were simulated in some load cases with conventional hydraulic systems and with three types of hybridized hydraulic systems. Different parts of the hydraulic systems were also analyzed separately. The analysis has shown that significant energy savings can be achieved by hybridizing hydraulic systems. The analysis showed that between 9-30% energy savings could be achieved by hybridizing the truck's various subsystems.

Abstract [sv]

Med dagens höga oljepriser och samhällets allt strängare miljökrav, stävar tillverkare av mobila entreprenadmaskiner efter att energieffektivisera sina produkter. Med detta i tanke formades ett projekt om att regenerera hydraulisk energi på entreprenadmaskiner. Syftet med detta projekt var att analysera vilka besparingar som kan åstakommas genom att hydraulsystemet på entrprenadmaskiner hybridiseras. En reachstacker truck (Kalmar DRD450-80S4XS) simulerades i några lastfall med konventionellt hydraulsystem samt med tre typer av hybridiserade hydraulsystem. Olika delar av de hydrauliska systemen analyserades även var för sig. Analysen har visat att stora energibesparingar kan åstakommas genom att hybridisera hydraulsystem. Den genomförda analysen visade på att mellan 9-30% energibesparing kunde uppnås genom att hybridisera truckens olika delsystem.
