Multidomain Model Integration for Online Collaborative System Design and Detailed Design of Complex Mechatronic Systems

摘要

Model integration enables the automated data flow of design changes between multidisciplinary models and improves the efficiency of collaborative multidisciplinary design. In this study, a geometry-related profile of SysML is first proposed to specify the geometric information of mechanical structure to support the generation of initial CAD models from SysML models. Second, a model comparison-based method is introduced to obtain the model changes to facilitate the incremental update between distributed heterogeneous models. Third, a multidisciplinary design optimization based method is introduced to deal with the design conflicts that hinder model integration during multidisciplinary design. Finally, a five-bar robot is used as a case study to demonstrate the whole proposed method.
