| 要約: | This research concerns the energy efficiency and speed improvement in the
hydraulic actuation system. Energy saving potentials in both the spool valves and the
hydraulic cylinders were investigated in the FLUENT code. The probable sources of
energy losses in these components were explored and the solutions were proposed.
The spool valve was optimised and improved by the elimination of sharp comers
and flow restrictions in the valve. Different geometrical modifications have been
proposed and simulated. Modification of the spool body geometry and the inlet port
geometry showed very little improvement. While the modification of the outlet port
geometry with conical surfaces, and showed good improvement regarding the
pressure loss. |
