Non-pneumatic tire with curved isolated spokes for agricultural machinery in agricultural fields: Empirical and numerical study

Soil compaction by tires of agricultural machinery severely affects field crop growth. In this study, nonpneumatic tires (NPT) were used in agricultural machinery. Experimental, empirical, and numerical approaches have been used to study the effects of NPTs on soil compaction. Random pneumatic tires...

description Soil compaction by tires of agricultural machinery severely affects field crop growth. In this study, nonpneumatic tires (NPT) were used in agricultural machinery.
