A Rig for Testing the Soft Soil Performance of Track Systems

For a given level of performance the track and suspension system of a military tracked vehicle must be as light and compact as possible to maximize weight and volume available for crew and payload armour protection, weapon and communication systems, ammunition, fuel, etc. Although track systems have been used on military vehicles for some seventy years method for predicting their performance in soft soil - and actual performance measurements - are limited and, even with its shortcomings, the nominal ground pressure term remains the performance comparator most commonly used by vehicle designers. This is partly because of the complexity of devising, proving and using improved methods and partly because military vehicle testing and training areas tend to be on sandy frictional soils where tracked vehicles rarely exhibit mobility problems.
