Projektbeschreibung:
Derzeit nur in englischer Sprache verfügbar
We are investigating model reduction of a finite element model of a spindle head configuration in a machine tool. The special feature of this spindle head is that it is partially driven by a set of piezo actuators. Due to this piezo actuation the resulting model is a second order differential algebraic system of index 1. The index 1 character allows the application of sparse low rank ADI techniques, whereas the second order form of the system can be treated in similar ways as the systems that appeared in the FVV and WAZorFEM projects. The long term goal of the research activity is to extend the approaches to higher index mechanical systems.
