In respect of the sampling process of the hollow-external-screw drill stem for automatic drilling sampling mechanism,the mathematical models between the cohesive force,friction coefficient of lunar-soil and the lunar-soil depth are built separately;the relationships between drill stem kinematic parameters(drill stem drilling speed and rotary speed)and the structural parameters(drill stem spiral angle,outside diameter,groove width ratio and spiral grooved depth in the drilling process)are also established.Th...
