摘　　要：对某研制阶段的高膛压火炮发射穿甲弹研究发现,当静强度安全系数较大时多次发生断弹事故,这说明此时动强度已成为主要矛盾,应用模态实验技术研究了脱壳穿甲弹动态特性,获得了该脱壳穿甲弹结构模态参数,模态分析方法所获得的动态薄弱截面位置与试验弹断弹情况相吻合,为其发射故障诊断提供了实验依据。The development stage of a high-pressure bore artillery projectile launchers found that when the static strength of a larger safety factor when a number of shells off the accident, dynamic strength at this time that this has become a major contradiction. Modal testing techniques is applied to investigate the vibration characteristics of the projectiles, The modal parameters of the projectiles have been obtained, modal analysis obtained by the dynamic cross-section weak position with the bomb test off bombs coincided with the situation, the launch of its failure to provide a diagnosis based on the experiment. There parameters provide scientific basis for the diagnosis of projectiles troubled-shooting.
