Abstract

Experimental data on the motion parameters of a steel spherical impactor whose diameter is 13.5 mm and which 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 impactor motion near a sandy obstacle and in a sandy medium, thereby allowing 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.

接触法在砂质介质中冲击运动的实验研究

摘要

给出了直径为13.5 mm的球形球形冲击器的运动参数的实验数据，该球形球形冲击器在沙质介质中以1470 m / s的速度运动。感应传感器和PIV（粒子图像测速）方法用于记录撞击物体在含沙障碍物附近和在含沙介质中的运动，从而使人们可以通过对沙面的高速视频记录来形象化地表波。获得表征冲击器在沙质介质中的运动和表面波传播的参数值。
