Construction of Experimental Track for Reproducing Accident Conditions Using Actual Tractor and Measurement System on Tractor Behavior （Part 1）

Abstract

The object of this study is to develop an experimental track for reproducing accident conditions using an actual tractor and measurement system on tractor behavior employing the optical motion capture system. The platform can reproduce two accident situations: 1） side-overturning under where the upper side wheel travels toward an obstacle on a slope. 2） Side-overturning from deviating from an operating road and dropping. The results of an overturning tests using a remote controlled 7.7 kW tractor demonstrate that it can perform overturning test repeatedly without breaking. We also devised a protocol to ensure measurement accuracy.
