High-Speed Impact Action on Movable Bodies

In this paper action of high-speed impact on the target, which could rotate, is examined. Target is designed for using as conduct-of-fire trainer; its screen is fired by light bullet from pistol. Target material is high-strength steel, material of bullets – lead and steel. Target is mounted on the shaft by means of sleeve-type journal bearings in such way that it is in equilibrium in the vertical position. When the bullet is colliding with target, last rotates at some angle depending on a friction in bearing and impact force. The purpose of this work is target parts designing in respect to the strength and rigidity under impact action of bullet. Estimation of the dynamic deflection of axial rod was carried out with Plaxis 2D-v8 dynamic modules program (Delft, the Netherlands). The field test of design target – measurement of shaft deflection – is executed
