Simulation Analysis of Soil Resistance of White Asparagus Harvesting End Actuator Baffle Parts Based on Discrete Element Method

摘要

In this paper, the baffle in the end effector of white asparagus harvest is taken as the research object, and five different baffles were designed. The discrete element method was used to analyze the resistance of different baffles when entering the soil. The simulation test results are as follows. The resistance of these five baffles depends on the depth and velocity of the incoming soil and is a quadratic function of these two factors. When the depth of the baffle into the soil is less than 6 cm and the velocity of the baffle into the soil is 0.2 m/s, the resistance of the inclined cylindrical baffle is minimal. When the speed is 0.4 m/s and 0.6 m/s, the rectangular inclined sheet-like baffle has the least resistance. When the depth of the baffle into the soil is greater than 6 cm, the resistance of the triangular plate baffle is minimal regardless of the speed. This study can provide a theoretical basis for structural parameter optimization of white asparagus harvest end effectors.
