Application of Multidisciplinary simulation and optimization of mechatronic systems in the design process

Dynamic and thermal properties crucially influence the attainable accuracy of machine tools. Therefore, dynamic loads and thermal influences on structural components and on translatory and rotatory feed drive systems of a machine tool are important factors to be considered in the design optimization process of mechatronic systems. This publication describes the integration of CAx-tools to enable a fast and efficient modeling and optimization of machine tools. Through the development of customized Finite-Element- and Multibody-Analyses, the dynamic state of components is monitored. Based on a FEA-extension, an analysis of thermal influences on machine tool movements was also conducted in computational models. Using experimental research the models have been verified. Through the developed method, an estimation of the Tool Center Point (TCP) shift can be determined.
