Modeling and Simulation of Certain Type Turret Based on Finite Element Method

摘要

The turret is subjected to a huge impact load during the firing of the gun. Therefore, the stiffness of the structure of the turret body in the launching state is the key problem to be considered in the design. In this paper, based on the turret model of a certain infantry combat vehicle, the modal analysis of the turret is carried out by using the finite element method. The natural frequencies and modes of the turret are obtained. On this basis, studied the stress and deformation of the turret under the launching load. The results show that the vibration of the turret structure accords with the vibration characteristics of the shell structure, but exhibits the local vibration characteristics. The maximum equivalent stress of the turret is distributed near the trunnion of the bracket during the firing process.
