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1-4 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 the projectile was analyzed, and its finite element model was built. Inertial bayonet-chamber process at 1~4 m/s was computed, the elastic-plastic deformation and dynamic response was obtained and the influence of the friction coefficient to the computed results of inertial bayonet-chamber process was analyzed.
