Abstract:
The traditional practice of finite element analysis of gun components w as on the basis of single part, it cannot accurately simulate the mechanics behavior of some gun components w ith mult iple parts such as breech mechanism. The principle and methodology of assembly level f inite element modeling and analysis of gun breech mechanism w ere put forw ard in this paper. A f inite element modeling and analysis of the assembly of a breech mechanism in locking condit ion w as carried out with special finite element techniques such as contact element , gap e-l ement and spring element . Those yield a more effect ive means for the evaluat ion of strength and st iffness design of g un breech mechanism.
