Technique of Uncapping System of Box Ring-Like Pressure Mine Girder for Sail Mine

To meet the structure and launch requirements of deep autonomous attack mine, a technique of uncapping system of box ring-like pressure mine girder for sail mine is presented. The composition, function and characteristic of uncapping system are described, and the critical parts of the system are analyzed and calculated by using finite element method. The related action process of the spread of ring-like pressure mine girder and the motion of sail mine is analyzed with simulation interference. Theoretical calculation and simulation interference analysis show that the system can solve four actual problems and meet operational requirement.
