In order to improve the jet penetration capability and jet performance, the grey correlation analysis on performance parameters of biconical liner is carried out. This paper simulates the jet formation process by using the AUTODYN finite element analysis software, and deals with the data by various dimensionless methods. At the same time, the influence of 5 structural parameters of liner on the jet head speed and jet length is analyzed by using the grey correlation theory. The analysis results show that the main factors affecting the jet are the material density of the liner, the cone angle of the small cone angle liner, and the high ratio of the upper liner. In the study of shaped charge, it is necessary to select the appropriate dimensionless processing method to obtain the optimal correlation sorting.
