Simulation in the Design of Machine Tools

A framework of methods for efficient and accurate simulation of the dynamics of machine tools including control is presented. The major achievements are a model order reduction technique with pre-definable error bound and a method for modelling of moving interfaces on flexible bodies based on trigonometric interpolation of the desired force distribution. The software tool MORe (Model Order Reduction and more) that implements thesemethods is presented. Application examples on analyses of dynamic and static properties are presented and simulation results are compared with measurements. The very good validation results confirm the usability of the presented methods and software for real-world applications.
