Directional stability of an agricultural tractor

چکیده
The discrepancy between the plow width and tractor leads to asymmetry of plowing units. geometry plowshare surface moldboard contributes generation lateral forces on working tool. All this imbalance tool deviation from straight-line movement during plowing. To maintain movement, driver has adjust machine every 5-10 meters, which is highly tiresome. study causes slips unit, we constructed a mathematical model, consists equations controlled tractor's uncontrolled shear under action external plow. description force interaction drive with ground based theory friction, taking into account anisotropy elastic properties in contact. Based passive hodograph diagram maximum side We found that reaches its friction value only case translational shear, when line passes through center gravity. In all other cases, shift (slip) caused by lower force. formulated features assumptions model as applied caterpillar wheeled tractors. As result, that, regardless direction displacement plow's traction resistance, slipped towards plowed field. result numerical experiment showed main reason for slip unit difference soils along sides but not resistance.

Tractor Operators’ Perceptions of Farm Tractor Safety Issues and Implications to Agricultural and Extension Education
Historically, the purpose of farm safety and health educational materials and programs has been to persuade, convince or educate farmers, members of their families, and hired employees to voluntarily engage in safe behavior during farm or nonfarm work activities (Murphy, 1992). Increasingly, authors have noted that traditional farm safety educational programs have been relatively ineffective (A...

متن کاملGuidance system for agricultural tractor with four wheel steering
In a typical automatic guidance system for agricultural machines, the guidance system controls only one degree of freedom; either the steering angle of the front wheels of the tractor or other steering equipment is used for steering. In a tractor with the multiple degrees of freedom, like four wheel steering, the guidance system may use both the degrees of freedom for path tracking. However, th...
