Impact Effect Analysis of a Special Blade Missile Hitting a Car Target

To explore the impact destruction process of blade missiles hitting automobile targets, the model including a blade missile and a car is established based on the structural characteristics and the combat environment. According to the Mie-Grüneisen equation of state, the Johnson–cook material constitutive and damage failure model are used for the blade missile and automobile. Then, finite element software is applied to analyze the penetration process, and the dynamic response of the blade missile hitting a car is calculated with different initial velocities and incidence angles. The results show that the penetration area is positively correlated with the incident angle at a certain velocity. However, the energy carried is still great after completing penetration at high initial velocity of the missile. these results provide an important theoretical basis for the development of the blade missile.
