Influence of Front-class and Back-class Thickness in the Whole Series of Liner on Jet

To increase the effective jet of liner and the depth of penetration into steel targets,three kinds of structures of series of liner were designed related to different liner's front and back class thickness.The finite element software LS-DANA was used to simulate the formulation and penetration of the jet of different kinds of structures,and then the experiments were carried out accompanying with the appropriate quantity of explosive charge.The results indicate that when the charge structure with liner's thickness proportion is 0.05 mm∶0.1 mm,it can get a higher jet tip velocity and a deeper penetration into the steel targets,and that the results are satisfactory in comparison with the numerical simulation and experimental studies.
