Life Prediction of Naval Gun Barrel Based on Multi-source Information Fusion
Abstract:The performance of naval gun barrel highly influences the operational lifespan. During the firing process, it is a quite challenge to predict the life of the naval gun due to many unknown factors in the complex physical and chemical reactions that occur in the barrel inner surface. This paper presents an optimized life prediction model which considers the information difference of ablative and fatigue life.The model consists of three modules, heat transfer simulation model, fatigue finite element model, and da… Show more
