Abstract
This work presents a new method for efficient FE modelling of machine tools and their mechanical components, called CoFEM (Component oriented Finite Element Modelling). It uses predefined component models, which, similar to modern CAD software, are gradually and hierarchically assembled to a more complex FE model using a bottom-up technique. The implementation and testing of CoFEM is done in the ANSYS environment. In this paper the modelling methodology and practical examples of modelling complex ball screw feed drive systems as well as single components such as rolling contact linear guides are presented. Advantages of the presented CoFEM modelling method compared with standard modelling methods are reduction of complex models to simpler subcomponents, decrease of modelling error probability, more flexibility regarding model changes and intuitive management of model versions.
