【 摘 要 】

In the process of projecting, the coupled property of warhead shell and charge is an  important issueof the launching safety study. To maintain charge in close contact with the shell is one of the requirementsfor quality. For solid-liquid mixed charge , its tensile strength is very small, the dynamic response characteristicbetween warhead shell and charge make it possible to form instantaneous void between the shell and charge.his paper studies the impact of factors of instantaneous void and its development law by numerical simulation.This work lays foundation for warhead charge quality control and projection safety.
