Simulation research of high-speed pill to damage close missile´s fuel cabin with full fuel

In order to research the anti-damage character of missile fuel cabin, the article in detail analyzed the geometry structure and damage characteristics and established the physical models and the finite element models of missile´s fuel cabin, simulated and calculated the invasion and damage process of high-speed pill damaged missile´s fuel cabin with ANSYS/LS-DYNA soft which was a large finite element model soft, the calculate had very small error. Simulation was well tallied with experiment on foundation of analyzing experiment data, it proved that the whole process of high-speed to intrude into missile´s fuel cabin was reappeared when appropriate material model was selected, the research could instruct the design of missile´s fuel cabin and the research of anti-missile.
