单体大幅宽铧式犁犁体曲面仿生减阻设计与试验
Biomimetic Design and Experiment of Plow Body Surface for Reducing Draught Force of a Single Large-width Moldboard Plow
摘要
Abstract
To address the issues of large draught force and high energy consumption in moldboard plow tillage,the scale structure of pangolins and the dermal denticle structure of sharks were taken as bionic prototypes to design a coupled bionic moldboard plow body surface.Based on the Moore-Coulomb soil shear theory,the composition and action mechanism of draught force were clarified through theoretical analysis,with a focus on bionic drag reduction targeting the frictional resistance between the soil and the surface of the plow body.The drag reduction effect of the coupled bionic moldboard plow body surface and the reliability of simulation results were verified through a combination of discrete element method simulation and field experiments.The simulation results show that under a tillage speed of 1.5 m·s-1 and a tillage depth of 150 mm,the coupled bionic moldboard plow reduces draught force by 14.75％,and increases the soil disturbance area by 4.22％compared with the traditional moldboard plow.This indicates that the coupled bionic plow body significantly reduces draught force while ensuring effective soil disturbance.The field test results show that the coupled bionic moldboard plow reduces draught force by 13.57％and increases the soil disturbance area by 2.62％compared with the traditional moldboard plow.The field test results are highly consistent with the simulation test results,which verify the drag reduction effect of the bionic design and the reliability of the simulation model.The research results provide a theoretical basis and technical solution for the surface drag reduction design of single large-width moldboard plow body.关键词
