One-pass Performance of Vehicles on Fine-grained Soils
Author: Clifford J. Nuttall
Publisher:
ISBN:
Category : Soils
Languages : en
Pages : 158
Book Description
Results are presented of an investigation of the one-pass performance of self-propelled vehicles in natural, weak, fine-grained soils for the following purposes: (1) to develop a reliable strength index for fine-grained soils with which predictions may be made of the performance of a vehicle on its first pass on a straight, level course, and a nominal vehicle load index to be used with the soil strength index to establish whether or not a vehicle will go; and (2) to provide means to predict one-pass drawbar pull and slope performance in soils having strengths in excess of the minimum required for one vehicle pass on level terrain, the increment of soil strength index necessary to permit a vehicle to maneuver freely, and the probable maximum speed of a vehicle operating in a terrain situation where the soil strength index exceeds the net vehicle load index. First-order answers are proposed to the five basic questions utilizing minor adaptations of techniques and concepts developed in the 50-pass trafficability work, and defining modified 'vehicle cone indices' (VCI1) and soil 'rating cone index' (RCI1) procedures appropriate to the one-pass problem. The ratio (VCI1/RCI1) is used as the basic soil loading numeric in simple approximate calculations of drawbar pull grade performance, soil strength increments necessary to permit free maneuvering, and probable maximum speeds, all as influenced by soil strengths.
