摘　　要：基于弹塑性有限元接触理论对弹丸惯性卡膛过程进行了理论分析,建立了弹丸惯性卡膛过程的有限元模型。对弹丸在1 m/s-4 m/s卡膛速度下的惯性卡膛过程进行了分析计算,明确了卡膛过程中弹带的弹塑性形变规律和弹丸的动力学响应,并通过计算分析了摩擦系数对卡膛过程计算结果的影响。Based on the elastic-plastic contact finite element theory,inertial bayonet-chamber process of a projectile was analyzed,and its finite element model was built.The inertial bayonet-chamber process with 1~4 m/s was computed,the elastic-plastic deformation of the band and the dynamic response of the projectile was obtained and the influence of the friction coefficient on the computed results of the inertial bayonet-chamber process was analyzed.
