Modeling of peat tractor semi-trailer motion

Abstract

Abstract Wheeled tractor vehicles are used to transport peat from open cast mines to storage stockpiles or processing facilities. This paper analyzes dynamic stability and control of an articulate vehicle. A mathematical model of linear dynamics is demonstrated for deformed supporting base and a two-tier transport unit consisting of an AWD tractor and a two-axle trailer. The functions obtained from analysis of maneuverability of the transport unit may be used in studies of operational and technical properties of the vehicles as calculation formulas to determine the trajectories of its components when transporting peat materials in peat mines. This analytic approach provided understanding of the propulsion system of the tractor vehicle and grounds for subsequent computer modeling of the process.
