Automation of Cross-Country Locomotion Model.
Abstract
This report explains how the user can operate the cross-country locomotion model in a conversational mode using a teletype connected to a GE-435 computer. The analytical model permits the user to predict the performance of any specified conventional ground-contact vehicle over any selected terrain in terms of average speed in miles per hour, average fuel consumption in gallons per mile, and delivery rate in ton-miles per hour. The computer code, written in FORTRAN 4, consists of a main program and three subroutines. The first subroutine, AREAL, considers terrain characterized by a specific combination of slope, soil strength, and homogeneous distributions of trees and microgeometry features; the second subroutine, LINEAR, considers elongated depressed features such as streams, ditches, etc.; and the third subroutine, SPECIF, considers surface irregularities of uniform or nonuniform size, shape, and spacing. Use of the main program and three subroutines is demonstrated by examples. These examples were obtained by using data files compiled for five military vehicles and terrains selected from data files or input as requested by the subroutines. The user has the option to substitute new values for selected vehicle characteristics as an aid in vehicle design studies.
