摘　　要：针对引信弹道适应性问题,以美军“战斧”对地攻击巡航导弹为例,采用有限元仿真和数值计算相结合的方式,研究导弹末端弹道意外触地、落水2种极限工况下引信的弹道适应性问题。研究结果表明:意外触地条件下,引信感受到的过载较大,能可靠起爆战斗部;意外落水条件下,引信感受到的过载较小,存在不能起爆战斗部的可能;该研究方法可供引信设计和生产单位借鉴。Aiming at the problem of fuse trajectory adaptability, taking the “Tomahawk” ground-attack cruise missile as an example, the finite element simulation and numerical calculation were used to study the fuse trajectory adaptability under the 2 extreme conditions of missile terminal trajectory accidental touchdown and falling into the water. The results show that under the condition of accidental touchdown, the overload felt by the fuse is larger, and the warhead can be detonated reliably;under the condition of accidental falling, the overload felt by the fuse is smaller, and the warhead can not be detonated;the research method can be used for reference by fuse design and production units.
