摘要
In order to study the drag reduction mechanism of bionic ribbed subsoiler, this paper established a soil particle motion analysis model by using discrete element analysis software EDEM, simulated the three kinds of subsoilers at the same tillage depth, the same tillage angle and the same tillage speed, compared the microscopic normal force and tangential force between the subsoiler and soil particles from the microscopic angle, and explored the drag reduction reason of bionic ribbed subsoiler according to the particle motion velocity nephogram and the particle motion trajectory on the subsoiler on different ribbed surfaces.
