Research on Reliability Analysis of Axial-Symmetric Vectoring Exhaust Nozzle Based on Parametric Modeling

Abstract According to the motion characteristics of Axial-Symmetric Vectoring Exhaust Nozzle (AVEN), its process is divided into convergence deflection adjusting piece A8 sub-mechanism and expansion A9 sub-mechanism. Taking as an example, proposing a method based on Solidworks-Abaqus-Adams multi-software platform establish rigid-flexible coupled parametric model run simulation analyze influence different factors accuracy mechanism. Basing Monte Carlo sampling algorithm design program automatic solution that separated from Adams platform. Under condition meeting certain requirements, degree automation in greatly improved. Finally, probability distribution performance parameters mechanism obtained, reliability calculated. The research results show when considering various influencing factors, will have corresponding deviations, which impact
