A CRITIQUE ON THE PERFORMANCE OF OFF-ROAD VEHICLES FULL-SCALE TEST RESULTS AND PREDICTION METHOD EVALUATION.

Abstract

A review of the literature pertaining to the prediction and experimental validation of off-road vehicle performance and an attempt to evaluate the various theories of performance prediction is presented. Categories of interest include drawbar pull, gradability, soil resistance to motion and speed. A total of 757 tests and corresponding predictions (in all categories) are reviewed and analyzed using a statistical measure to assess the prediction validity. Only full scale tests are included. Tests of single wheel elements in soil bins is a subject for possible future study. It is found that the state-of-the-art of vehicle field tests needs considerable improvement. Field testing presents many difficulties which must be resolved if reliable and meaningful data are to be collected. It is apparent that past test exercises were not planned and implemented specifically for the purpose of theory validation. (Author)
