Modeling and validation for modern complex mechatronic systems

© IFAC. The increasing demand for light weight, fast and precise mechatronic systems while reducing the time to market dictates to use advanced simulation and analysis tools in the design process (Jönsson et al. [2005]). This paper presents the on-going activities on the simulation and validation of combined 1D and 3D models for the design and analysis of complex mechatronic system. This includes the development of a flexible multi-body model, a lumped parameter driveline model and a control system. In order to demonstrate the potential of the virtual design and analysis process for modern mechatronic systems, an industrial machine tool is used as a case study. In order to predict the dynamic behavior of the machine, forecast the influence of specific design changes, and assess the impact of different control architectures with full confidence, the model needs to be validated. To this end, the simulations of the model are compared with the results obtained on a physical prototype.status: publishe
