Theoretical Study on Breakdown Damage of High-speed Objects
Based on the current research status of the high-speed moving object model ,the paper establishes the ground coordinate system ,the impactor coordinate system and the impactor velocity coordinate system suitable for the impact process,and deduces the transformation relationship between the relevant coordinate systems. Then,based on the theory of impact ,a theoretical model of impact process is established. The influence of the shape of the impactor ,the Angle of impact and the thickness of the target on the impact effect is simulated. The theoretical calculation shows that the closer the impact Angle is to the front ,the better the breakdown effect is and the less difficult it is. The larger the thickness of the target ,the higher the breakdown difficulty. It provides a theoretical basis for the study of the breakdown damage process of high-speed objects.
