| Abstract: | Evolvable aimed warhead can make all the fragments toward the target and help the air-to-air missile reaching the greatest damage to the target. This thesis studied the transient response of a kind of evolvable structure join by explosion, designed the experimental scheme, carried out the static detonation experiment, established a 3D model of evolvable structure using DYNA, and numerically simulated the deployable process of the evolvable structure with explosively driven load using the method of ALE. The results of experiment and numerical simulation prove the reliability of experiment scheme and the feasibility of the numerical simulation method. |
