摘要

•Using Hertz-Mindlin with JKR model to express the adhesive properties of soil.•Bionic grouser can significantly reduce the deep-sea soil adhered to mining machine.•Both experiments and simulations verified the self-cleaning effect of bionic grouser.•Surface modification of grouser can improve self-cleaning performance.
