Based on the incompressible theoretical model of magnetically driven solid liner experiment, the magnetically driven solid liner experiment on FP-2 device was simulated and analyzed. The simulation results show that，there is structure coefficient in the boundary magnetic induction intensity formula of magnetic driven solid liner with reflux hood structure, whether it is a two-dimensional magneto-hydrodynamic theoretical model or other theoretical models such as incompressible that. By simulating the experiment of magnetically driven solid liner experiment with different thickness and radius, the law of structure coefficient of magnetically driven solid liner experiment is studied. The structure coefficient of magnetically driven solid liner experiment is not only related to the liner’s radius, but also related to the liner’s thickness. The larger the inner radius of liner, the smaller the structure coefficient of magnetically driven solid liner experiment with reflux hood structure, and the larger the thickness of liner, the smaller the structure coefficient of magnetically driven solid liner experiment with reflux hood structure. The understanding of the structural coefficient law in magnetically driven solid liner experiment is helpful to the accurate design, prediction and research of these experiments such as magnetically driven solid liner, magnetically driven cylindrical impact compression and magnetically driven cylindrical quasi-isentropic compression.
