On Dynamic Resistance of the Composed Sledge in Antarctica
From September 1968 to February 1969, the 9th JARE (Japanese Antarctic Research Expedition) traveled to the South Pole with the aid of snow vehicles and sledges. In order to ensure the mobility of the travel, the tractive effort of the snow vehicles on the crust surface of snow in Antarctica and the...
