摘要
The projectile’s engraving process is nonlinear and transient, which affects barrel life and shooting accuracy. To reveal the mechanism of projectile / gun interaction, a dynamic engraving resistance model is developed by combining theoretical analysis, experimental study, and numerical simulation. Using explicit dynamic finite element method and Abaqus software, the dynamic engraving process of the projectile is simulated. Using the multi-parameter synchronous measurement technique, dynamic engraving experiments are carried out to verify the validity of numerical simulation. Based on the completely inelastic collision assumption, the dynamic engraving resistance model is established. The model includes the effects of material static strength, dynamic deformation resistance, and high-speed sliding friction, and is connected with projectile movement and structural parameters of the projectile / gun. Besides, results of the established model are compared with numerical simulation results, and the key factors affecting engraving resistance are analyzed. The results show that the dynamic engraving resistance first increases and then decreases. It reaches its maximum at the moment when the projectile’s cylindrical part is completely engraved in the chamber throat. In addition, projectile velocity and volume change rate are two key factors that affect engraving resistance. The proposed theoretical calculation results are in good agreement with the simulation results, which verifies the accuracy of the theoretical model and provides theoretical foundation for the optimization of light weapon systems and design of barrel structures. © 2022 China Ordnance Society.
