Simulation and experimental study on drag reduction and anti-adhesion of subsoiler with bionic surface

A new subsoiler with placoid scale microstructure bionic surface was proposed which mimicked shark skin to reduce tillage resistance and soil adhesion during subsoiling cultivation. The contour curves of on were fitted, two kinds continuous discontinuous microstructures designed fabricated, respectively. effects different surfaces investigated by finite element simulation experiment. results indicated that the reduced horizontal vertical force 21.3% 24.8%, can prevent between more efficiently.
