Abstract
The purpose of this paper is to make a calculation model for agricultural tractors excited by tire lugs in order to consider tractor vibration characteristics. We identified model parameters using the experimental results to construct six-DOF tractor model. We define the excitation from tire lugs to be assumed displacement amplitude of road irregular. The amplitude was identified by the results of on road running tests, which carried out using one lug tire and three non-lug tires. Comparing the calculation results with the experimental for the usual tractor, we can show the validity of the proposed model and identified parameters.
