Abstract:
Considering the contact impact between interacting components especially cylindrical rollers and raceway inside and outside the seat ring,a nonlinear finite element dynamic model of a large caliber gun is established to study the dynamic response of the gun seat ring during gun firing.Static analysis of the seat ring is made based on traditional theory.The static analysis results of the finite element method are compared with those of Hertz theory,and the correctness of the finite element method is verified.The dynamic contact problem of the seat ring under launching load is analyzed using dynamic implicit integration algorithm,and the variation rules of contact force and contact pressure of the seat ring are obtained.The dynamic analysis results of the finite element method are compared with the static analysis results of traditional theory.The results show that the maximum contact force and the peak contact stress obtained by the finite element method are greater than traditional theory calculation results by 30% and 45% respectively,traditional theory has certain limitations in force analysis of gun seat rings,and the analysis results of the finite element method are more suitable for actual formations.
