Measurement and Evaluation of Mechanical Properties of Drill Propulsion Mechanism on Fresh Snow Slope

Abstract

In this paper, the mechanical properties of a drill with an applied Archimedean Screw on a fresh snow slope were experimentally evaluated. This drill is used for a snow exploration robot, and it was conducted as part of the verification of the robot's ability to move on a fresh snow surface. A full-scale model of the drill was placed on a snow surface with a known slope, and the amount of settlement and slip (the amount of movement parallel to the slope) were measured by applying a load to it. As a result, it was confirmed that the phenomena were different from those on the flat snow surface, and it was clarified that the machine for the slope needs to be improved.
