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
