Multidomain Systems: Electronic, Hydraulic, and Mechanical Subsystems of an Universal Testing Machine Modeled with Modelica

The Simulation of hydraulic or electronic systems has been state of the art for a long time. For both of these domains there exist highly specialized simulation programs which can be regarded as a kind of industrial standards. Often problems arise if different domains of technology occur within one system and very detailed models are needed. As an example a universal testing machine is presented which consists of hydraulic, mechanical, and electronic component systems. Each component is modeled fully detailed using the Modelica language [1]. Without coupling of simulators the whole simulation model can be investigated by one tool.
