Research on Applied Technology in the Optimization of the Naval Gun Bracket with Mechanical Properties

Abstract

In the paper, the three-dimension model of the naval gun including barrel, cradle, bracket .etc has been built in the environment of Pro/E, which Provides the necessary conditions for the building of the dynamics equivalent mode. Then, finite element analysis software ABAQUS had been used to create the finite element model of the naval gun. Apply the above model to simulate the process of shooting with an angular altitude of zero. The characteristics of structural dynamics response of the gun are obtained through analysis. Through the comparison from the result, the stiffness and strength of the naval gun is verified and the basis to improve the firing accuracy is provided. With the method of this thesis, much work such as verifying scheme, finding design bug, verifying firing accuracy, evaluating stiffness and strength of the gun can be done through simulation in the stage of gun design, then period of design is shorted and cost of design is also reduced.
