To make clear the dynamic behavior of the rubber crawler system, the constants of dynamic spring and viscous damping of a crawler were measured at 12 points between adjacent two core bars, with the system being excited on a vibrating table with a certain range of frequency.
Results certified that the higher the frequency, the bigger the dynamic spring constant while the viscous damping constant became smaller. Both constants varied between core bars with a similar tendency as the static spring constant.
Further, a dynamic three-dimensional model of a crawler vehicle driving on a solid horizontal surface was proposed, and its motion equations with these physical parameters were obtained which enable to estimate the dynamic driving characteristics of the vehicle.
