Parametric Finite Element Modeling of Rifled Barrels with Bore Damage

Abstract:

Rifled barrels exhibit highly complex internal geometries and inevitably undergo wear and erosion damage under high-temperature, high-pressure, and severe friction conditions during service. Accurate and efficient finite element modeling of rifled barrels with different damage states is therefore essential for investigating projectile engraving behavior and interior ballistic performance. In this study, an automated parametric finite element modeling method for rifled barrels and damaged barrels is developed in a Python environment. By directly generating node and element data and exporting standard INP files, the proposed method eliminates geometric inaccuracies and topological inconsistencies. A graphical user interface is further developed and packaged as a standalone executable, allowing user-oriented visual parameter input and rapid generation of both intact and damaged barrel finite element models. Using the generated models, barrel-projectile coupled finite element simulations are conducted to investigate the effects of different barrel damage periods on projectile engraving resistance, in-bore motion, and muzzle exit characteristics. The results show that bore damage significantly degrades the centering capability of the rifling, resulting in increased projectile center-of-mass displacement and nutation angle during interior ballistics. The proposed parametric modeling framework provides an efficient and robust tool for interior ballistic analysis and damage sensitivity assessment of rifled barrels.
