Scale Model and Full-Scale Vehicle Testing in Cohesive Clay Soils

Abstract

Vehicle performance tests were conducted in low-, medium-, and high-cohesion disaggregated clay soils through a wide moisture content range in an attempt to correlate off-the-road performance of models to full-scale vehicles by the use of the similitude theorem. The investigation included a study of all soil parameters that could affect vehicle performance in these soils. The effects of vehicle weight, tire design, speed, slip, and soil characteristics on drawbar pull and tire sinkage were determined for all three types of soils for a complete range of moisture content levels. Correlation between full-size vehicle performance and scale models can be accomplished by using proper scaling factors.
