Construction of Experimental Track for Reproducing Accident Conditions Using Actual Tractor and Measurement System on Tractor Behavior （Part 2）

Abstract

This study establishes a method for measuring the dynamic behavior of a tractor using the experimental track and measuring system described in Part 1 of this report. On the motion capture software, a stable measurement of the behavior of the center of gravity can be ensured by placing the virtual point at an intermediate position between reflective markers, which were fitted on the right and left side of the center of gravity of the tractor. The motion capture has measurement values with precision equivalent to that of an inertial measurement unit about vertical acceleration and 3-angle angular velocity. It is possible to measure the dynamic behavior and torsion of the front and rear axles and the center of gravity.
