Research on dynamic characteristics of gun turret under launching load

Abstract The purpose of this study is to further the dynamic characteristics gun turret under firing load. Firstly, relative motion between inner ring and outer was decomposed into axial translational motion, radial rotational freedom in two orthogonal planes order solve problem large number ball bearings complex contact calculation actual structure ring. Then, equivalent mathematical model established. Based on finite element method, Bushing with body-body connection type, Multi-point constraints algorithm Deformable Behavior attribute. stiffness set as linear stiffness, response simulation action load carried out. acceleration sensor arranged at left trunnion position turret, generated by transient force during measured position. results showed that test value 1304.38m /s 2 ,the 1425 m/s , error 8.46%, which verifies accuracy indicates can reflect well.
