Abstract: When studying the launching environment of a pre carved projectile belt, this paper constructs centrifugal safety mechanism models of the grenade barrel, the projectile body and the fuze based on a 35 mm gun grenade through Solid works. After assembly, the launching dynamics model of the gun grenade is established by importing ADAMS software. After the launching environment is established in ADAMS software, the motion process of the projectile in the bore is simulated, some parameters of the motion of the projectile in the bore are obtained, and the arming time of the centrifugal safety mechanism is simulated. The simulation results show that the centrifugal safety mechanism is released after the expiration of the launch after effect period, which meets the fuze design requirements and provides a reference for fuze mechanism simulation.
