System architecture is important for the design of complex mechatronic systems since it acts as a connection between conceptual design and detail design. An efficient automatic system architecture generation method is imperative for successful system design. However, some deficiencies remain, such as the omission of function-component mapping, the component combination explosion etc. In this study, an automatic system architecture generation method is proposed. First, the unified model of architecture information is established and two mapping manners are proposed. Then, the set of components which can realize the same function are further filtered and evaluated according to specific requirement. Finally, the compatible components are combined together to fulfill the overall function of the product. This method is supported by ontology knowledge base, and has good visual effect using SysML, which enables system designers to design a product efficiently. A case study is provided to demonstrate the feasibility and efficiency of the method.
