In the previous paper, the mechanical interaction between the track rollers and the rubber crawler regarded as a cause of machine vibration has been made clear by experiments. Furthermore, an equation of spring force changing according to location between the two core bars has been led from relationships between the loading forces of the track rollers and the vertical compressing displacements of the rubber crawler.
In this paper, a mechanical model for the rubber crawler system was proposed in order to investigate quantitatively the effect of the machine vibration on the mechanical interaction between the track rollers and the rubber crawler, and equilibrium equations were obtained. Thus, driving simulation on a solid horizontal surface was carried out by using the equilibrium equations so as to estimate machine vibration such as pitch, roll and bounce in case of modifying the number and location arrangement of the track rollers.
