In order to verify the jet forming characteristics of the shaped charge with a truncated-liner, numerical simulation and X-ray experimental research were carried out. The behavior of the truncated-liner and the top velocity, diameter and morphology of the jet were obtained, and the outcomes were compared with the characteristics of the jet formed by the traditional shaped charge. The results show that the numerical simulations are almost consistent with the results obtained by the X-ray test. The morphology of the two is nearly the same, and the data deviation is less than 6%. The truncated-liner can effectively improve the velocity of the jet head, which can reach more than 10km/s by structural optimization. In addition, the truncated-liner can decrease the diameter of the slug, meanwhile, increase the length of the jet and the quality utilization of the liner.
