Open publisher page 0 citations

Abstract

A new multi-row cylindrical liner structure was proposed against the penetrating targets and characteristics of mine.It can be seen as 8 symmetrical cuneiform liners connecting each other.The process of the multi-row cylindrical liner forming jet flow under explosion load was simulated by nonlinear finite element software.The results show that the new liner could form jet flow,which realized expected imagination.The research results can provide a new selection for study on mine warhead.
