Results of continued activities on developing and verifying the method for computer design of the safety and arming device are given. On the basis of the mathematical model of the motion of the safety and arming device given in [1], program code SADFOR for resolving of the differential equations of the motion of the clock mechanism and numerical simulation of its function was developed. Some calculation results with variation of significant parameters of the clock mechanism construction, due to its optimization as well as the arming time performed, are shown. Results of experimental testing of the real model of the mechanism construction that satisfied all functional characteristics as well as the safety performance, thus confirming the quality of the developed method, are also given.


Key words: fuze, arming device, clock mechanism, safety device, numerical simulation, artillery projectile, construction optimizing.
