Calculation of the energy balance of complex hydraulic drives

This paper presents an approach to calculate the energy balance under consideration of variable technological parameters which allows to calculate the energetic behaviour of a hydraulic drive by means of the state variables supplied by dynamic simulation. In this method, the energetic behaviour of a hydraulic drive can be determined by means of the state variables supplied by dynamic simulation. A cross roller drive is investigated as an example for use. Hereby, a really available drive is analyzed according to functionality and energy balance in comparison with alternative drive variants. All variants are compared and evaluated. To evaluate the drives' energetic behaviour, there are considered the magnitude of power dissipation and the efficiency in various working cycles and technological parameters.
