Aiming at solving the problems of the structural design and the applicability of the penetration performance of dual-mode warhead， a dual-mode warhead with arc-cone combined shaped liner of variable wall thickness is designed. Using ANSYS / LS-DYNA simulation software， the influence of shaped charge structure parameters on the characteristic parameters of dual-mode damage elements is studied. Based on the optimized structure， the damage of different damage elements to concrete targets is studied. Through the range analysis， the optimal combination of the structural parameter of dual-mode warhead is obtained： the cone angle of the liner is 80°， the arc radius is 8 mm， the upper wall thickness of the liner is 2.22 mm， the lower wall thickness is 5.44 mm， the length-diameter ratio of the charge is 0.88， and the shell thickness is 5 mm. The X-ray imaging test is carried out to verify the optimization results. The results show that the simulation results are in good agreement with the X-ray test results. Compared with the shaped charge jet （JET）， the rod-shaped charge jet （JPC） has obvious advantages in surface collapse and opening performance when penetrating concrete targets， while the penetration depth of JET to concrete targets is significantly improved compared with JPC. The research results can provide reference for the design and application of warhead structure.
