Research on Manufacturing Process Reliability of Spacecraft Honeycomb Sandwich Structure Panel
According to the reliability requirements of the spacecraft honeycomb sandwich struc-ture panel such as manufacturing efficiency,form and position accuracy,bonding strength and embedded parts pulling force,the control content of the process design with the direction and re-quirements of process improvement are defined by establishing four typical manufacturing process reliability models according to the characteristics of the manufacturing process,including series model based on manufacturing process flow,sequence correlation model based on manufacturing process unit,network correlation model based on manufacturing process parameters and func-tional correlation model considering inspection process.Through the analysis of common failure modes and causes,the analysis results of reliability model are further verified,and the improve-ment measures of manufacturing process are clarified.Therefore,in actual production,the ma-nufacturing process is optimized and serial manufacturing units are reduced through parts stereo-typing.By optimizing the process parameters,curing the process state and applying automatic in-telligent process equipment,the manufacturing deviation is reduced,and the product reliability and production efficiency are improved.
