Abstract

Tractor rollover is a very serious issue considering the safety of heavy tractors, which can have significant financial and environmental implications. Therefore, to ensure the safety of people and property, we need to know more about the static and dynamic characteristics of these vehicles. In this paper, we conducted a literature study on the stability analysis of tractors to analyze the static and dynamic characteristics to ensure the safety of roads and drivers. In this paper, it is shown that the stability test method of the tractor can be analyzed more quickly through the 3D model through various calculation methods in the actual vehicle-centered test method using the tiltable platform. In addition, it was observed that the rollover stability decreases because the increase in the center of gravity (COG) affects the static stability factor (SSF) of the vehicle. Depending on the attachment state of the farm machinery, the overall center of gravity and the center of gravity of the tractor are different, and it is necessary to analyze the models of various machines applying them. Therefore, it is possible to analyze the dynamic stability of tractors with various attachment types as well as topography of routes.
