Experimental study of the impact interaction of a rigid wedge and ice

Abstract

 To conduct computational assessments of the stress loading of vehicle with rotary-screw propulsion unit (RSPU) parts and the level of the shock/vibration impact on the crew and passengers, the characteristics of the contact interaction between the parts of RSPU and ice as the support surface are necessary. One of the characteristics of this interaction is the energy spent on the destruction of ice, related to the volume of the destroyed ice.

An experiment was conducted to determine the specific energy of ice destruction upon impact by a pointed body with a shape close to the shape of the RSPU helical ridge. The results obtained make it possible to use them in the virtual simulation of the movement of an all-terrain vehicle with a rotary screw propulsion unit on an uneven ice surface.
