Track's Slip either Relative Difference of Displacements (RDD) During Dozer's Turning

The field investigations of SG-15HS dozer turning were described in this paper. Mutual dependency between slip and relative difference of displacements (RDD) was tested both for separate signals from left and right track and for theirs mean value. The procedure of using two side measuring wheels was shown and then discussed. Its advantages and disadvantages were pointed out as well as range of proper applying of this. The possibility of using GPS for calculation of track?s displacements was analysed.
