The Explosion Reactive Armor On The Mechanism Of Long-rod Projectile

This thesis has discussed the function mechanism of explosive reactive armor and the dynamite of reactive armor. Then under certainly of the assumption term, it has played the research of the interference of explosive reactive armor to APFSDS, and used the simplification model of the function, which can describe the degree of interference of explosive reactive armor to APFSDS, and proceeded with the calculation of explosive reactive armor of three kinds of different projects.Then, applying finite element method of numerical analysis, we have had dynamic analysis of the interference of explosive reactive armor to APFSDS Built up the finite element model of the interference, and process a lot of calculation with the use of finite element analysis software ANSYS/LS-DYNA. So we achieve the relationship between different impact point of reactive armor and velocity, angle and length of APFSDS. In the same time we achieve the relationship between different the moment of explosion of reactive armor and velocity, angle and length of APFSDS. Making use of the above two conclusions by way of the preliminary condition, we achieve depth of penetration and distance of penetration of APFSDS in the interference of explosive reactive armor. At last, we compare and contrast the above conclusion with the experimentation data of explosive reactive armor.
