In the modern era, the demand of energy saving is increasing more and more while the natural resources have been exhausted. Among various possibilities, some methods to recuperate energy during vehicle swing motion have been widely examined. After providing required drastic design changes, electric and hydraulic hybrids designs have shown a great improvement in fuel efficiency. The rotating movement of excavator is called swing or slew and is driven hydraulically. The swing drive is hence driven by a hydraulic motor creating a rotating motion. Following the movement of a joystick, the pump is controlled to match the spool positions, swiveling out. In the proposed system, swing braking time the remaining fluid will save as energy by a simple accumulator. This remaining save energy will be used in the system from accumulator. The proposed system is considered as secondary by using two combination of transformer (motor & pump combination) and have some dissimilarities from the conventional swing system. Furthermore, the paper simulates variable inertia and show the effect of variable moment of inertia in different simulation result .The proposed system will be developed in AMESim software. The proposed system will be more efficient in saving energy.
