针对某攻坚弹立靶密集度散布偏大问题，在分析了该攻坚弹结构特点和发射过程的基础上，采用故障树和对比分析方法对立靶密集度散布偏大的原因进行了分析，最终确定攻坚弹尾翅片卡槽缺口形状由直角改变为弧形导致了攻坚弹尾翅箍在膛内提前脱落，尾翅片提前张开，碰撞变形环或制动环，使弹丸在膛内受到扰动力，从而在飞行时偏离正常轨迹，这是立靶密集度散布偏大的根本原因。对此进行了试验，试验结果和分析结果一致。

In accordance with the questions of large dispersion of vertical target density for hard structure munition,the paper analyzed structural features and launching process of the hard structure munition,then adopted fault tree analysis and comparative analysis to analyze the reasons of large dispersion of vertical target density.It finally confirmed dimensional change that from right angle to arc of card slot nick of tail fin of hard structure munition to cause tail fin hoop of hard struc-ture munition drop early in the chamber,tail fin spreads early,then crashed distorted hoop or brake hoop,proj ectiles were subj ected to disturbing force,deviates from its normal flight path,which is the basic reason of large dispersion of vertical target density,tests it as well,test results match analysis results.
