An Analytical Model for Predicting Cross-Country Vehicle Performance. Appendix B: Vehicle Performance in Lateral and Longitudinal Obstacles (Vegetation) Volume 1, Lateral Obstacles
Abstract
A total of 95 lateral obstacle tests were conducted with two tracked and three wheeled vehicles at the NASA Marshall Space Flight Center, Miss., and Eglin Air Force Base, Fla. The principal conclusions from these tests were that (a) vehicle performance in terms of speed made good in an array of vegetation assemblages can be correlated with the density of vegetation assemblages expressed as mean obstacle spacing, (b) the minimum obstacles spacing required to permit movement of a vehicle can be computed from vehicle width, and (c) the speed made good a vehicle can achieve when maneuvering in lateral obstacles is significantly affected by the slope of the terrain. Methods of determining mean obstacle spacing from structural cell diameter and percent area denied from stem diameters of trees, vehicle width, and structural cell diameter are shown. A method of determining percent area denied by logs, mounds, and other obstacles is suggested.
