Lateral Stability Performance of Articulated Narrow-Track Tractors

A tractor losing lateral stability starts to rollover. It is a matter of fact that rollover accidents are one the most frequent causes death and injuries for farmers. Consequently, tractors fitted with specific protective structure minimize consequences driver during (ROPS). The narrow-track tractor, designed operate in vineyards orchards, category very narrow track width risk higher. aim study was evaluate compact types commercially available, mount cantilever engine forward position effects on Center Gravity (CoG) because more than 50% weight loaded front axle, and, specifically, articulated where affected by pivot point connecting two bodies. As consequence typical design tractors, steering action line passing through rear tire contact points ground changes, influencing tractor’s stability. approach research based reproducing condition developing kinematic model, goal virtually simulate behavior calculate angle tractors. innovative contribution this paper articulation joint modeling, assuming virtual reproduce relatives’ rotations between bodies tractor: vertical (yaw angle) longitudinal (roll rotations. lowest value 39.3°, measured at −35° yaw angle. model stage will allow adjusting parameters improve performance.
