Oct 21, 2020 · These tests do not include hydraulic energy recovery. A backward-facing simulation of an 18 tonne excavator is described. The simulation uses input data collected from grading and lorry loading duty cycles. Applying the workbus system architecture to the excavator in simulation, fuel savings of 31% to 48% are realized.

The theory of the excavator's hydraulic system was elaborated in the paper taking a 20t hybrid hydraulic excavator produced by a domestic company for example. The rotary movement of the hybrid hydraulic excavator was achieved by a newly developed electric motor, fuel consumption could be reduced as the result of the speed inhibition when the excavator standby.
