| 摘要： | A vehicle traveling through snow is required to expend a greater amount of energy than is necessary when traveling on a rigid surface. Visually, this energy difference can be explained by the formation of a rut. Various attempts have been made in the past to equate the energy of compaction to vehicle motion resistance. However, many of the previous models use information gathered through the application of a vertical force (with a plate-sinkage device) to predict the horizontal motion resisting force. In an attempt to more accurately quantify the relationship between snow compaction and vehicle motion resistance, a vector anslysis of compaction by a wheel is performed. A method for separating tha compaction due to vehicle weight and forward thrust (borisontal propulsion) is suggested. Two mothods of using this compaction force breakdown with fleidgenerated data are proposed for the calculation of vehicle motion resistance in shallow snow. |
