Study on Tractor Behavior Based on Accident Topography

Abstract

In this study, a behavior simulator of a tractor in an actual accident site was developed. The dynamic behavior of the driving tractor in slant topography was represented by movements of four degrees of freedom: vertical, pitching, rolling, and forward. Therefore, a dynamic equation of four degrees of freedom was developed. A representation method to simulate the tractor behavior was developed using the topography data obtained from the survey and hearing around the accident site. Furthermore, we identified the parameters of tractor behavior based on experiments. The behavior simulation was performed using the original code. We discussed the practicality of the dynamic equation to realize tractor behavior and also the practicality of the representation method of the topography.
