Fatigue Analysis of Spike Segment of Special Tractor Wheels in Terms of Design Improvement for Chernozem Soil

The driving wheels affect the tractive efficiency, fuel consumption, and soil compaction. This study presents fatigue analysis of a spike segment that is main part an innovative designed to improve tractor performance. design improvement was proposed for Chernozem allowing full penetration spikes. loaded by forces resulting from maximum drawbar pull at 100% wheel slip penetrometer resistance. A increase caused tires also calculated. experiments were performed using subcompact in first gear on grass field moisture 18.8%. Gerber theory used ANSYS software. dependances safety factor horizontal rod diameter number load cycles constructed. 1.73 calculated made steel S355 suitable reduction actual (12 mm). showed 1.28 100,000 case reduced (10 8 mm simulated, but factors do not allow it terms safe operation.
