“…By analyzing the kinetic energy of the disturbed particles, the power required for soil cutting can be obtained indirectly, which can be used to evaluate the digging performance of the bear claw bionic shovel (see Figure 7) [45]. Based on the velocity field, by analyzing the sinking performance and resistance of the tools in the sand, the structure and parameters of the tool can be optimized [37][38][39]. The contact models such as elastic HMCM and plastic HSCM are usually used to analyze the velocity field of soil particles under the action of tools [40].…”

The discrete element method can be used to analyze the interaction between tools and soil. It can be used to guide the optimal design of tools, but the appropriate simulation and test method selected is important to achieve the goal. This paper mainly introduces the disturbance of soil by tillage tools. The disturbance of the soil by tools include soil loosening, soil movement, and soil mixing. The disturbance contour is used to visually display the disturbance results, and the cross-sectional area, lateral soil throwing amount, ditch ridge height, ditch width, and ditch backfill are used to characterize the cross-sectional shape. Tracers are usually used to track soil particles to visually display the particle movement path during disturbance; this can be used to study the soil disturbance trend by the tools. When parameters and models are appropriate, the movement and contact of microscopic soil particles can be accurately simulated. By comparing the particle behavior of simulation and experiment, the contact model and contact parameters can be verified. The method introduced provides a reference for the optimal design of the tools and the research of disturbance by the tools.
