Land target design scheme based on typical ship structure features

  Objectives  The aim of a ship's land target is to provide a judgment basis for the actual penetration and damage ability of anti-ship warheads on the warship structure. At present, the penetration capability of anti-ship missiles is calibrated by its penetration of steel plates with different thicknesses.

  Methods  In this paper, the damage mode of an anti-ship missile penetrating a typical ship deck structure is studied via numerical simulation. The damage mode and motion law of the plate differ from those of the previous thick target. Based on the movement of the ship's plate frame and the actual failure mode of the ballistic missile based on the ship's land target, a multiple land-based ship structure design scheme is proposed which takes the material characteristics, dynamic boundary conditions and objective conditions into consideration.

  Results  Through the numerical prediction of the designed land target, the damage pattern of the target and the motion law of the missile are similar to those of the actual situation.

  Conclusions  Land targets can respond to the actual strike ability and damage effect of missiles on surface ships.
