Abstract
The Author reported on the slip sinkage phenomenon of the tractor drive wheel in the previous reports.
In this paper some discussions are done about the results obtained in the experiments which were held in the same way as shown in the ones already reported in the previous reports.
Theoretical discussions were done prior to the experimental ones. The following relations were obtained as the function of slippage s of the tractor wheel.
η=-0.302s+11.8 (Fig. 3)
γ=-0.233s+27.5 (Fig. 4)
α=0.266s+26.4 (Fig. 5)
ε=α/β=0.017ht+0.225 (Fig. 6)
h0=0.57s+3.44 (Fig. 7)
pmax=-0.11875ht+9.5 (Fig. 8)
β=38° (Fig. 9)
In these relations, slippage s is giving big effects on the other factors such as η, γ, … etc. and they can be expressed as the first order function of slippage s.
