穿甲弹发射故障的动态诊断

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 coin...
