  3. Consulting about foreign study, the research showed that the speed of firing can be improved by modifying the machanism of the automatic, and at the same time two problems must be solved, one is that more mechanisms should act at the same time to reduce the time of the whole actions of automatic mechanisms, the other is that the time of each mechanism ' s action should be reduced. the time can be reduced by several ways. the first one is to reduce the mass of mechanism, the second one is to increase the force applied on the mechanism and reduce the resistance, the third one is to shorten the working distance, the fourth one is to give abstention and cushion to mechanism before action ends. this thesis includes the following topics : discussion of the theory of the automatic and shell - swing design, establish the kinematic and dynamic models of the main structures in automatic and perform the corresponding mechanical analysis, set up a compendious cyclical diagram for the automatic ; the computer simulation to the navy gun ' s firing parts
