Tracked-Vehicle Drawbar Pull on Soft Soil

摘要

This document describes the procedures for determining the drawbar-pull characteristics of tracked vehicles on soft soil (sand and fine-grained soils). Drawbar pull on soft soil provides an important measure of vehicle mobility during operation over adverse terrain. It represents the power available beyond that required to overcome soft-terrain power losses such as track slippage, ground resistance to motion, and hull drag resistance. (Results from sand-course testing are directly comparable; results from testing in fine-grained soils require a correlation study).
