Application of digital human modeling order to determine the fatigue and discomfort feeling of the tractor driver

Abstract

Driver fatigue has a negative impact on driver performance. Modern transport vehicles have become more and more advanced and that is why there are increasing demands for driver comfort. Tractors play an important role in agricultural production, but their working environment can cause a feeling of discomfort. The tractor seat must provide a comfortable position for the driver and does not affect his health and safety. While driving, drivers feel certain vibrations that cause discomfort, back pain and fatigue.A Mc Cormic D326 tractor was used for the analysis. Drivers Fatigue analysis was performed on ten male subjects of the Serbian population. The obtained results showed that the influence of anthropometric data affects the occurrence of fatigue and back pain. A large correlation was observed between the subject's height and fatigue, while a weak correlation was observed between shoulder width and discomfort feeling.
