Abstract
The paper aimed to analyze the dynamic response of a new type penetrating missile in rotary attacking warship. The dynamic response characteristics of the penetrator become more complex when attacking the ship target due to the special materials of the deck such as stiffeners. Therefore, different from attacking other targets, the article reveals the design rules of precession penetration ammunition and fuze. A physical model of the missile target is established to study the numerical simulation of the penetration process of rotating projectile into a stiffened target based on finite element analysis (FEA) software. We studied the dynamic response characteristics of different projectile positions, rotational speeds, and positions that act in precession penetration. As experimental results show, the residual velocity of the precession penetrator decreases with the distance between the projectile point and stiffener. When the projectile penetrates the second target plate, the acceleration is greater than that in the first layer. It is proved that the deflection angle of the shell body is affected by comprehensive factors. The rotational speed in the projectile has less contribution to precession penetration ammunition. In addition, the change of acceleration in the missile’s central section can be significantly perceived in the direction perpendicular to the penetration direction.

Summary
Literature [2] introduced rotating penetrating missile numerical simulation and experimental in bunker buster. Literature [3] introduced an investigation of the penetration resistance of monolithic and double-layered steel plates. Literature [4] introduced an experimental and numerical investigation on the ballistic resistance of double-layered steel plates. Literature [5] introduced a computational investigation of ballistic impact behavior and penetration resistance of a nacre-like ceramic/polymer-laminated composite. Literature studies [6,7,8,9,10,11] introduced the response of different protective materials during penetration and revealed the relevant laws. Literature studies [12,13,14,15,16] introduced the analysis and experiments of antiship target penetration and revealed relevant laws. It can be seen that there is relatively little research in the ship of the rotating penetrating, and the relevant laws are not clearly understood, which has caused certain constraints on the design of the rotating penetrating missile
