原始语种摘要: Abstract(#br)Due to the increasingly severe soil compaction and plough pan thickening prevalent in agricultural practice, an increase in operating energy consumption and a decrease in crop growth has been observed. This paper aims to solve the problem of heavy tillage resistance by using riblet structures extracted from shark scales in the design a biomimetic shark-inspired (BioS) subsoiler. To produce better quality work, the design parameters of the BioS subsoiler, including the ratio of the riblet height to the riblet spacing h/s , the riblet height h , and the internal friction angle α, were considered, and a mechanical analysis of the relationship between the BioS subsoiler and the soil was performed to evaluate tillage resistance, total energy consumption and soil disturbance. The...
