Mechanical Analysis and Experimental Research of Working in the Earth Helical Blade

Abstract:

Based on the Rankine earth mechanics theory, the mechanics model that the helical blade working in earth is simplified in this paper, and an experimental platform for discovery the relationship that between helical blade structure parameters and the driving torque is designed when the helical blade working in the earth. Through a series of experiments, comparative analysis the effect of the helical blade width, pitch on the driving torque, the experimental results verified the feasibility of the helical blade operation way of working in the earth, which laid the theoretical foundation for the subsequent development of the spiral in the earth device.
