摘要

With the continuous increase in product complexity, a single design method is no longer able to cover the entire design cycle of the product, especially complex mechatronic systems. This paper presents a closed-loop integrated design framework for complex mechatronic system, aiming to improve its design efficiency and quality. The proposed integrated design approach is user-oriented, while leveraging a variety of design tools to provide comprehensive support throughout the process. This framework merges design structure matrix (DSM), Kano model, functional expression and axiomatic design theory. DSM and Kano are utilized to classify and analyze the requirements of the complex mechatronic system. Functional expression visualizes the mapping process between the requirement domain and the function domain, and establishes corresponding functional models. The optimal functional integration solution is further selected through evaluation to proceed with subsequent structural design. A design case of weight deviation detection system of complex-shaped rebar is performed to demonstrate its effectiveness.
