  1. Success in optimizing the obturating performance of the obturator of the breech mechanism shows that the method and technology for optimal design of nonlinear multi - component structural system with contact put forward in this thesis is effective and practical . structural optimization problems that are difficult to solve through the optimization method available in the universal cae software can be accomplished by means of this method
  2. Comparison of stiffness , strength and obturating performance of the initial obturator of the breech mechanism with those of the optimized one is made , which indicates that the stress concentration that leads to fatigue failure in the optimized structure is eliminated . the flexibility of the optimized obturator of the breech mechanism is considerably increased and its obturating performance is substantially improved
