First, the phenomenon of the projectile-retarded mechanism of moving plates is introduced, the conditions of the projectile-retarded mechanism of moving plates is analyzed. By a number of numerical simulations, the residual length and residual velocity of the rod which penetrate the fixed plate is contrasted with those of the moving plate. Under the different velocity of moving plate, the relationship between the effect of the projectile-retarded moving plates with thickness and intersection angle of the projectile-retarded moving plates is achieved, and the most optimal thickness and intersection angle is gotten.
