Applications of Discrete Element Method in the Research of Agricultural Machinery: A Review

As a promising and convenient numerical calculation approach, the discrete element method (DEM) has been increasingly adopted in research of agricultural machinery. DEM is capable monitoring recording dynamic mechanical behavior materials operational process machinery, from both macro-perspective micro-perspective; which tremendous help for design optimization machines their components. This paper reviewed application status two aspects: First model establishment common such as soil, crop seed, straw, etc. The other simulation typical processes or components, rotary tillage, subsoiling, soil compaction, furrow opening, seed fertilizer metering, harvesting, so on. Finally, we evaluate development prospects on look forward to promoting its field
