Abstract
On soft terrain, such as deep snow, track sinkage often exceeds vehicle ground clearance and the vehicle belly comes into contact with the terrain surface. This paper describes the results of a detailed investigation into the effects of design features, particularly the combined effects of initial track tension (i.e., the tension in the track system when the vehicle is stationary on a level, hard surface) and vehicle belly attitude (nose-up or nose-down), on soft ground mobility of tracked vehicles. The investigation was carried out using the latest version of an advanced computer simulation model, known as NTVPM, developed under the auspices of Vehicle Systems Development Corporation. The results show that the initial track tension has a significant effect on soft ground mobility, particularly when track sinkage is greater than vehicle ground clearance. When the vehicle belly is in contact with terrain surface, its attitude also has a notable effect on vehicle performance at low initial track tensions. However, its effect on mobility decreases with the increase in initial track tension. It is demonstrated that NTVPM is a useful and effective tool for design and performance evaluation of tracked vehicles from a traction perspective.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
