Performance-Oriented Conceptual Design of Fastener Joint Configurations for Aerospace Equipment

The joint configuration design of aerospace equipment requires a comprehensive balance of multiple factors, yet the process is often complex and time-consuming. Moreover, the Function–Behavior–Structure (FBS) conceptual design model lacks specificity for aerospace joint design. To address these issues, a Function–Performance–Structure (FPS)-based design method for joint configuration is proposed. Service performance is introduced as a bridge to map functional requirements to structural characteristics, thereby establishing a complete FPS conceptual design framework. Based on this, a conceptual design methodology for aerospace joint configurations is developed using typical aircraft structures as the research object. To verify the effectiveness and reliability of the method, a typical joint configuration is selected for instance validation. By integrating conceptual modeling with structural joint design, the proposed method offers a novel approach for aerospace joint configuration design, providing a theoretical foundation to enhance both the innovation capability and engineering value of aerospace equipment design.
