Summary:Basing on the application background of anti-submarine torpedo using shaped charge technology, a new structure of shaped charge liner named focusing annular liner was designed. The Autodyn-2D software was used to simulate the jet formation of this liner underwater. The result shows that: Through two times of convergence, the focusing annular liner can form one jet, this jet is thicker than normal jet. And during Secondary convergence, jet velocity and collision pressure are greatly increased.
