| dc.description | Abstract: Four light snow vehicles of the personnel carrier type were used to test the trafficability of the snow cover at the Keweenaw Field Station near Houghton, Michigan, in February and March 1955. It was found that the maximum drawbar coefficient, (drawbar pull/vehicle weight) was obtained at a track slip of 20-40%, indicating that drawbar pull is a function of the frictional resistance of the snow. The Kamm-type 30°-angle grouser attached to the M-7 tractor produced a significant increase in the drawbar coefficient obtainable. On the basis of an efficiency coefficient, the M-7, with or without angle grousers, outperformed the ladder-type tractor. The maximum efficiency coefficient occurred at lowest track slippage. A modification of Coulomb's equation was shown to express a relationship between tractive effort and vehicle weight. The angle of internal friction, ϕ, varied between 26-32° with a mean of 28°. In these trials the relationship between tractive effort and load appears to be defined by Coulomb's equation for cohesionless materials, indicating that this snow acted as a cohesionless substance when trafficked. | - |
