Abstract

The function cycle of an automatic weapon is the key point for investigation of all activities carried out during firing [1]. Knowing the force of recoil and the corresponding action time helps in studying the dynamic characteristics of a weapon. In old techniques; recording of function cycle depends mainly on studying the motion of the breech block carrier, upon which basic dynamic characteristics are berried and can not be represented. These omitted characteristics represent impacts, strain resulting from impacts, as well as the forces causing instability of weapon during firing [2]. The difficulty in recording these phenomena is referred to the difficulties of mounting the sensing elements on highly retarding components; especially in high caliber weapons. In this paper; a new technique based on recording strain signals resulting from impacts during motion of weapon mechanism is used. It allows recording all vital activities of function cycle and facilitates the analysis of forces generated from firing. The study allows to record and to analyze one of the most effective forces, this force is referred to as the recoil force of the whole weapon [3,4], it also helps in determination of the efficiency of muzzle devices used to reduce the effect of this force [5]. It has been taken into consideration that the measuring set up allows recording free and braked recoil force.
