A theoretical analysis was conducted and the mathematical model of the motion of safety and arming device consisting of the rotor (drive gear), two pairs of involute gears and pallet was developed. Mathematical model, developed on the basis of the equations of the dynamics of rigid material system and impact mechanics, includes differential equations of motion for coupled and free motion, as well as the phase of impact.
Key words: fuse, arming device, clock mechanism, safety device, mathematical modeling, equations for motion, differential equations, artillery projectile.
