“…The results such as the maximum VonMises stress, the shape of the extrusion resistance curve, the maximum extrusion resistance, and the duration of the extrusion resistance at different moments of engraving demonstrated in these results are very close to the results of the Sun [43] experiment. The RAME model used in this paper was developed by Wang et al [16,17]. The results of the RAME model are presented in Fig.…”

“…Through multiple shot simulations, we can obtain the total wear at each node of the rifling in the direction of the axis of the barrel, and thus the distribution of the rifling wear tired. The detailed calculation procedure can be found in the literature [17].…”

“…On the other hand, the research by Yang et al [8], Zhang et al [9,10], and others [11] ignored the extrusion of the banding process to optimize the interaction of the projectile in the rifling process; moreover, the firing accuracy improved through intelligent optimization methods [12], uncertain optimization method [8] and robust game theory methods [13] by Yang's group. In the field of rifling wear, a finite element model (FEM) of rifling wear was established by Ding et al [14,15], and Li et al [16,17] established a unified thermochemical erosion-mechanical wear model to achieve the prediction of the full rifling wear amount in the barrel and analyzed the influence of the structural parameters of the bore on the firing performance and service life of the artillery. However, these methods are all local stages of optimization of artillery firing performance, and cannot comprehensively and integrally optimize the comprehensive performance of artillery.…”

To enhance the comprehensive performance of artillery internal ballistics-encompassing power, accuracy, and service life-this study proposed a multi-stage multidisciplinary design optimization (MS-MDO) method. First, the comprehensive artillery internal ballistic dynamics (AIBD) model, based on propellant combustion, rotation band engraving, projectile axial motion, and rifling wear models, was established and validated. This model was systematically decomposed into subsystems from a system engineering perspective. The study then detailed the MS-MDO methodology, which included Stage I (MDO stage) employing an improved collaborative optimization method for consistent design variables, and Stage II (Performance Optimization) focusing on the independent optimization of local design variables and performance metrics. The methodology was applied to the AIBD problem. Results demonstrated that the MS-MDO method in Stage I effectively reduced iteration and evaluation counts, thereby accelerating system-level convergence. Meanwhile, Stage II optimization markedly enhanced overall performance. These comprehensive evaluation results affirmed the effectiveness of the MS-MDO method.

This paper simulates the launching dynamics of the Terminal-guidance projectile considering the barrel thermo-chemical erosion wear and mechanical wear. A thermochemical erosive material degradation model that considers the rise in friction temperature is first introduced. Moreover, the wear state of barrel rifling at different periods is calculated using the erosion wear model. A three-dimensional model of the worn barrel is established, and the coupled barrel– terminal-guidance projectile launch dynamics are simulated for different wear periods. Finally, the projectile's bore overload and attitude are analyzed to explore the effect of barrel wear on launch.

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 data fusion based on D-S evidence theory. The heat transfer simulation model and fatigue finite element model are established by simulating the firing process of a naval gun, and the life distribution is calculated. On this basis, a life prediction model is improved taking into account the variability of erosion and fatigue life data. The result shows that the established model can predict the life of the barrel more accurately and correctly judge the state of the body tube and improve the reliability of the naval gun.
