The mounting height of the wing is one of the key structural parameters of the winged subsoiler,which greatly affects disturbance behavior of subsoiling. The disturbance behavior and resistance under different heights of the wing(55 mm,75 mm,95 mm,115 mm and 135 mm) were compared and analyzed by the comprehensive use of EDEM and digitized soil-bin test. The results showed that with the increase of mounting height of the wing(MHW),the disturbance area of hardpan layer after subsoiling was increased first and...
