マルチチャンネルEHAのエネルギー効率に関する実験的検証

抄録

In previous research, we proposed a new hydraulic system named ”Multi-channel EHA” that can control multi-DOF by controlling a single pump and electromagnetic switching valves, and confirmed its potential experimentally. In the case of multi-DOF driving, the conventional hydraulic systems have a problem of heavy mass and low efficiency. On the other hand, the advantages of this proposed method are lightweight and high energy efficiency. Regarding the system mass, it is much lighter than the conventional hydraulic systems for multi-DOF drive with multiple pumps because the proposed system can realize multi-DOF drive with a single pump. In this paper, we experimentally verified energy efficiency and quantitatively compared it to conventional hydraulic systems.
