    Abstract
  • With the development of protection technology, the anti-explosion and anti-shock ability of modern ship has been improved increasingly. However, the conventional shaped charge torpedo warhead with common liner is difficult to damage modern ship fatally. Therefore it is necessary to improve the power of torpedo warhead for damaging enemy ships. In this paper, a kind of shaped charge warhead with two spherical combined liners is proposed based on the shaped charge warhead with tapered and spherical combined liners. The structure of warhead is designed, its working mechanism is analyzed, and numerical simulation is performed with the finite element analysis software ANSYS/LS-DYNA. The stress contour of a cylindrical shell target with embedded water layer in its penetration zone is obtained. Simulation result shows that the warhead with two spherical combined liners can provide moving space for the latter explosively formed projectile(EFP) by making use of the former shaped charge jet, which leads to higher destructive effect on target than that of shaped charge warhead with tapered and spherical combined liners. This research may provide a reference for design of new high-powered torpedo warheads
