Simulation environment for designing the dynamic motion behaviour of the mechatronic system machine tool

Abstract

Machine tools consist of mechanical and electronic components and software, and thus constitute mechatronic systems. To make sure that they work reliably in the overall system these different components have to be designed in coordination. This process is complicated by the fact that virtual prototyping is becoming increasingly important in machine tool design and every development department employs different software tools, e.g. finite element method, multibody system simulation, computer aided control engineering software, etc. Moreover, every department has its own method of setting up models within these programs. The result is that various sets of data are produced that are mutually incompatible due to different modelling methods. This paper describes a new method for setting up a model for the mechatronic system machine tool, with special emphasis on the design of its motion dynamics. The main objective of the method is to standardize the model set-up within the different simulation tools with a view to producing reusable data. A concept for data management and provision is also presented.
