应用模态分析方法研究了１００滑脱壳穿甲弹动态特性，获得了１００滑脱壳穿甲弹结构模态参数，为１００滑的故障诊断提供了试验依据。
The dynamic characteristics of the 100-arm shell-piercing projectile have been studied by using the modal analysis method. The modal parameters of the 100-arm shell-armor-piercing projectile have been obtained, which provides a test basis for the fault diagnosis of 100-slip shell.
