Abstract
Abstract Truncated liner shaped charge(TLSC) structure can form truncated hypervelocity shaped charge jet(THSCJ), which is significantly different from the ordinary shaped charge jet(OSCJ). The formation behavior of THSCJ is studied by numerical simulation and theoretical analysis. The results show that the additional liner can enhance the propagation of detonation wave and the improvement of jet velocity. The head velocity of THSCJ is obviously higher than that of OSCJ. The influence of liner structure on the formation performance of THSCJ is investigated by changing the protruding length of the additional liner and the height of the truncated liner. Within the given range of structural parameters, when the protruding length of the additional liner is 1.5mm, and the truncation height is 1/3 of the total height of the liner, the performance characteristics of THSCJ is more stable.
