摘　　要：为研究动能杆对TBM弹头的毁伤效应,根据文献调研将TBM弹头结构分为鼻锥、前设备舱、战斗部舱和控制舱四个部分,并分别建立了其等效结构模型。据此,通过Autodyn软件,仿真计算了动能杆以一定速度和不同着角对鼻锥、前设备舱和战斗部舱等效结构的高速撞击效果。结果表明:动能杆难以贯穿TBM弹头的鼻锥侵入弹头内部,但可侵入前设备舱对TBM弹头进行毁伤,且可有条件的引爆战斗部舱内的B炸药,并通过数值仿真获得了引爆条件。To study the damage effect of Ke-rod to TBM warhead, according to the literature research, TBM warhead structure can be divid- ed into four parts： nose cone, former equipment chamber, warhead compartment and control cabin. On the basis of the analysis, the equiv- alent structure models of the four sections were established. Therefore, through the Autodyne program to calculate the impact effect of Ke- rod to nose cone, former equipment chamber and warhead compartment with high speed and different angle. The results of simulation analy- sis show that Ke-rod can hardly intrude into TBM warhead through nose cone, but can make TBM warhead damaged by penetrating former equipment chamber, what is more, Comp. B in warhead compartment will be initialed conditionally and the detonating conditions have been got for detonating conditions.
