Research On The Damage Performance Of Combination Warhead Of Fragments And Discrete Rod To Cruise Missiles

With the birth and development of cruise missiles, the research of Missileintercept and damage is also conducted. The main anti-cruise missile warhead arefragment warhead, blast warhead, discrete rod Warhead, continuous rod warhead,multi-shaped charge warhead and cluster-type warhead. This paper designs thecombination warhead of fragment and discrete rod, the warhead has both theadvantages of the high speed of fragments and the massive of discrete rod. Based onthe process of research, Nonlinear dynamics analysis software ANSYSY/LS-DYNAis used to simulate the penetration of different materials, shapes, qualities andpenetration angles of fragment to cruise missiles warhead.And then analyzes theStraight and curved rod penetrate cruise missiles target-guided cabin with differentpenetration angles and touch angles. At last the damage performance of combinationwarhead of fragments and discrete rod to cruise missiles is simulatedThe results of the research show that (1) the damage of tungsten alloy fragmentsis stronger than4340steel fragments;(2) the detonation speed threshold about thefragments of different shapes on the cruise missile warhead is cube fragments>thesmall aspect ratio fragments> spherical fragments> large aspect ratio fragments;(3)penetration angle has the greatest impact on the detonation velocity threshold ofcylindrical fragment, followed by the cube fragments, it has minimal impact onspherical fragments;(4) if the penetration angle and touch angle of straight rod aredifferent, the damage to the target-guided cabin would be different, when penetrationangles40°≤≤60°、touch angles20°≤80°, the kinetic energy of the utilization ofthe rod is high, the damage on the cruise missiles target-guided cabin is the best;(5) ifthe penetration angle and touch angle of bent rod are different, the damage to thetarget-guided cabin would be different, when penetration angles50°≤≤80°, thedamage on the cruise missiles target-guided cabin is the biggest; when the bend rodpenetrate the target with different touch angles, they are all guided through the target-guided cabin and has an effective damage on the cruise missiles;(6) After theexplosion of the combination warhead of fragments and discrete rod, the fragmentsand rod can reach the desired speed, it would have a fatal injury on cruise missile.The research results can provide certain reference for the development ofanti-cruise missile.
