Travel resistance of the agricultural rubber crawler (Part 2): analytical simulation of travel resistance caused by rolling resistance of the track rollers

摘要

In our previous paper, it was certified that the rolling resistance of the track roller driving on the rubber crawler had a close relationship with the deformation phenomenon of the rubber crawler due to the vertical load of the track rollers. In this study, analytical simulation of the travel resistance was performed by using experimental results of the present paper and static equilibrium equations constructed by the mechanical model of the rubber crawler system. As a result, it was found that this simulation method was applicable to predict travel resistance by the rolling resistance of the track roller. Further, the rolling resistance for each track roller arrangement could be estimated quantitatively.
