Abstract [en]

To increase energy efficiency in construction machinery, energy recuperation systems are of great interest. For this purpose, the potential of using a secondary controlled excavator swing drive has been evaluated. Concepts for emergency brake operation and circuit architecture have been designed and compared in simulation. A wheel excavator has been considered as reference vehicle and dimensioning of the secondary controlled drive has been made to match the performance during a typical duty cycle. It has been shown that considerable energy savingscan be achieved in both open and closed circuit. The potential of the secondary controlled swing in comparison with a hybrid solution lies however in minimising the parasitic losses ofthe hydraulic circuit. A possible decreased energy consumption of up to 60 % for the swing drive can then be achieved by the recuperated energy.
