Tractor Dynamical Characteristics in Relation to Working Tasks and Energy Efficiency

Abstract

Depending on the agricultural operation and used implements, tractor perform different tasks. Therefore, tractor drawbar pull is of prime importance. In this paper influencing factors on the tractor tractive performance and energy efficiency are considered. An appropriate model to analyse tractor engine power parameters and fuel cnsumption is developed. Also, a simulation model is formed and used to investigate of the tractor unstady driving performance.

Zavisno od poljoprivredne operacije i korišćenih priključnih uređaja traktor obavlja različite zadatke. Pri tome, raspoloživa vučna sila je od najvećeg značaja. U ovom radu razmotreni su uticajni faktori na vučne karakteristike traktora i energetsku efikasnot. Razvijen je jedan prikladan model za analizu parametara snage motora i potrošnje goriva. takođe je formiran simulacioni model i korišćen za istraživanje karakteristika traktora pri nestacionarnom kretanju.
