Abstract

To provide exact mechanics input for anti-high-overload optimal design of penetration projectile, a projectile-target response model was built. On the basis of force analysis for penetration process, the rigid body motion model for projectile was established by adopting Newton’s second law. Then, numerical integration calculation was carried out, and the trend of each physical quantity in penetration process was obtained. To verify the credibility of the model, artillery test was carried out, and the complete penetration process was recorded by high-speed camera. Based on the result that the values of calculation agreed well with that of tests, it could be concluded that the model was more suitable to analyze force conditions, which could be applied to guide the optimal design of the projectile.
