The Store Automatic Fixing Equipment operates as an external force acting on fixing the Store during the flight and as a device designed to prevent the Store from being shaken when the aircraft is flying with the Store. In this paper, we derived the mathematical modeling of the Store Automatic Fixing Equipment through the analysis of the operating principles of the Equipment. The gap occurred by the external vibration forces was calculated through the mathematical model and structure analysis. And then the shape and stiffness design of the wedge, i.e., the Store Automatic Fixing Equipment was derived by the mathematical modeling and structural analysis. We made the Store Automatic Fixing Equipment and took the vibration testing under the aircraft flight conditions. We used the load cell to measure the reaction forces acting on the gap between the Store Automatic Fixing Equipment and the Store. The results of the reaction force measurements were compared with the analysis results of the design and the suitability of the Store Automatic Fixing Equipment’s design was verified based on the analysis.
