Performance of Soils under Track Loads. Report 2. Prediction of Track Pull Performance in a Desert Sand

摘要

A first-generation, quantitative description of straight-line track pull performance in a desert sand was sought by laboratory tests of a model track. Of 16 variables selected to provide a comprehensive description of the track-sand system, analysis of three Plackett-Burman (statistical) test designs showed four to merit initial study. (Author)
