摘要：The physical effects used to guide system design are becoming increasingly multidisciplinary. As a result, the undesired design coupling represented by undesired multidisciplinary physical effects is an intrinsic problem of great complexity in mechatronics design. However, little attention has been paid to address this issue. In this study, an efficient recognition method is proposed to obtain the undesired physical effects. In view of the importance of flows for the analysis of technical systems and technical processes, a flow-based representation is proposed to model both physical effects and components. Meanwhile, physical semantics is specified by various constraints applied on input/output flows to support physics-based reasoning. According to the representation, the output flows of components can be calculated to obtain flow distributions in the local influence area (LIA) based on interval-based logic to improve the computational efficiency. Within LIAs, undesired physical effects can be recognised by checking the related triggering conditions specified in physical effect knowledge base. A hairdryer example is used to academically demonstrate the proposed method.
