Abstract
A simulation model that describes an energy efficient hybrid log crane with energy recovery capability was developed. The lifting cylinder of the crane is operated by integrated electro-hydraulic energy converter (IEHEC). The system in question is a pump-controlled fluid power circuit. Pump-controlled fluid power circuits reduce energy losses in comparison to conventional valve controlled circuits. The model of the log crane is based on multibody dynamics. The model of the fluid power system is implemented in Simulink. The models are run synchronously on real-time. The developed simulation models enable to study the hybrid electro-hydraulic power transmission under varying conditions. With the setup described in this paper the suitability and profitability of IEHEC operated system can be tested virtually on any working machine. Due to the modularity of simulation models only the multibody model of the working machine must be regenerated to test IEHEC in different types of working machines.
