This paper reports on the results of the authors' research on the problem of simulating hydraulic drives. Two 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. An outlook on including thermal interactions will round out and conclude our deliberations.
