Abstract:
Experimental data on the motion parameters of a steel spherical impactor with a diameter of 13.5 mm that moves in a sandy medium at a velocity of 1470 m/s are presented. Induction sensors and the PIV (particle image velocimetry) method are used to record the motion of the impactor near a sandy obstacle and in a sandy medium, which allow one to visualize a surface wave via high-speed video recording of the sand surface. The values of the parameters characterizing the impactor motion in the sandy medium and the surface wave propagation are obtained.
Keywords:
high-speed video recording, contactless chronographic section, sand, PIV method.
