In this report, the torque of a powered wheel axle due to sinkage was theoretically discussed and validated experimentally by use of power tiller wheel (4.0-10 size).
Based on the assumption that sinkage of wheel is proportional to the torque loss of a powered wheel axle, the following conclusions were derived:
1) Torque loss of powered wheel axle per unit sinkage (1mm) was 0.686 percent (almost 0.7%).
2) Torque loss of powered wheel axle per unit slip sinkage (1%) was 0.3013 percent (almost 0.3%)
3) Torque loss per unit slip sinkage was less than a half of the one per unit static sinkage.
Soil condditiors in this experiment were:
internal friction angle of soil:φ=44° (degree)
cohesion of soil: c≈0 (kg/cm2)
hardness of soil at surface: 0.2-0.6kg/cm2
