THE EXPERIMENTAL-DIDACTIC STAND FOR THE ANALYSIS OF THE INFLUECE OF THE PARALLEL SET OF MAGNETORHEOLOGICAL DAMPERS ON THE RECOIL OF THE SLIDING UNIT

摘要

In this paper, the laboratory stand, dedicated for research and didactic purposes is presented. The stand allows investigating the parameters which characterizes the recoil effect in the 12,7 x 99 mm caliber arm. It is also possible to study the dependencies in the system with the parallel magnetorheological dampers, which are placed in the universal basis for weapon. The methodology of the research, as well as the experimental data and theoretical discussions concerning the components of the recoil force are provided. The part of the research devoted to the recoil effect was performed in a large-caliber arm configuration, which allows to fire shots in a laboratory conditions utilizing training bullets with reduced propellant charge. The experimental studies were also carried out for the rifle grenades. The results indicate the possibility of building a universal basis for 12,7 mm x 99 caliber weapons and can provide useful information for formulating the design assumptions for the controlled dampers with magnetorheological fluid, designed for special purposes.
