Abstract
When hydraulically driven machine is constructed it is often hard to study the effects of alternative hydraulic components and systems on its behavior because it is time-consuming to install and replace the components in the real construction. An effective and timesaving method is presented. The method is based on a real-time hydraulics simulation model which is simulated while running the real machine construction. The main idea of this method is to get the real hydraulics, connected with the mechanism, to behave like the virtual hydraulics does. When managed, the variations can easily be made in the simulation model and their effects then be seen from the behavior of real construction. Also, properties of mechanics like flexibility, gaps and friction quite often difficult to model are automatically included.
