Abstract
This paper reports on the results of the authors' research on the problem of simulating hydraulic drives using two selected examples. Two current developments of complex hydraulic drive systems are being used as examples for prototypical forming machines (the tryout press and spin extrusion machine). The means and methods used for the numerical simulation of the hydraulic systems will be presented based upon the developed model and we will then add a calculation of the energy flow in the system to these means and methods including statements on energy loss and the potential for storing and recovering energy. An outlook on including thermal interactions (within the system and beyond the borders of the system) will round out and conclude our deliberations. These tools were implemented in the Matlab/Simulink program system.
