Abstract: Accurate simulation of the interaction between soil and tillage tools can achieve partial replacement of field trials, which can not only improve efficiency and reduce costs, but also optimize tillage tools. In this paper, the research status of modeling and analysis of soil-tillage tool interaction is reviewed from two aspects such as classical mechanics analysis and numerical model analysis（including finite element analysis, discrete element analysis, fluid dynamics analysis and coupling algorithm analysis）. It is proposed that the simulation of soil in the modeling of soil-tillage tool interaction is not close to reality, the single modeling method has limitations on soil simulation and the problem of optimizing boundary crossing in multi-software coupling algorithm. By optimizing the boundary of different models in multi-coupling software, the accuracy of simulating the interaction between soil and tillage tools is improved, and the simulation results are closer to reality.
