Analytical Prediction of Vehicle Mobility Muskeg

Abstract

An experimental program was conducted on various muskeg areas in the Upper Peninsula of Michigan. This involved typical soil-strength measurements, including sinkage and shear, on various Radforth Classifications of muskeg; in addition, several special soil strength measurements were also made to supplement the conventional data. Two lightwight, low ground pressure tracked vehicles, M29C Weasel and Spryte 1301, were used in the verification tests. Towing tests were conducted at various speeds and the minimum resistance was found at 3 mph ground speed. Drawbar-pull tests resulted in maximum net tractive effort being generated at 25% slip. The results of these tests indicate that a large perimeter to area ratio on tracked vehicles is required for maximum mobility over muskeg.
