Abstract

Abstract: Aiming at the problem that the front cover of a certain type of launch canister with high comprehensive performance requirements, and the projectile body axis does not coincide with the geometric center line of the launch canister, through demand analysis, structural design, material selection and determination of forming process, then to simulation analysis, sample test verification, a kind of front cover with decentered breaking point was finally determined, in which epoxy resin foaming material was used for main body bearing structure. The success of relevant test examinations and subsequent ejection launch tests indicate that the special-shaped structures front cover of launch canister with breakthrough has good comprehensive technical performance, and meets the design requirements well.

Key words: breakable front cover, structure design, forming process, simulation analysis, test, composites
