茶园仿生掘耕刀具设计与试验OA
Design and experiment of bionic digging tool for tea garden
为解决现有掘耕刀具在茶园掘耕过程中存在阻力大、能耗高的问题,基于穿山甲爪趾开展掘耕刀具结构仿生设计,利用正交试验设计刀面仿生凸棱结构,并采用离散元方法研究不同参数组合对掘耕阻力的影响水平,获得最优组合参数:凸棱宽度为5.0mm,凸棱高度为3.0mm;使用最优参数开展全仿生刀具设计及耕作仿真分析,仿真试验结果表明,使用全仿生刀具可理论减阻35.4%.通过田间试验表明,使用全仿生学设计的掘耕刀具进行茶园耕作管理,实际可减阻30.6%,整体具有较好的减阻效果;同时,开展耕深、耕深变异系数等耕作质量指标对比分析,结果显示,全仿生刀具在减阻的同时还能够保持良好的耕作质量.
To address the issue of high resistance and energy consumption during the process of digging in the tea garden,this paper conducted a bionic design for the digging tool structure based on the toe contour curve of the pangolin claw.Orthogonal experiments were used to design a bionic convex structure on the tool surface and the discrete element method was employed to assess the impact level of different parameter combinations on digging resistance,the optimal combination of parameters was determined to be the convex structure width of 5.0 mm and the convex structure height of 3.0 mm,the optimal parameters were used to conduct fully bionic tool design and tillage simulation analysis.Analysis showed that the use of fully bionic digging tools could theoretically reduce resistance by 35.4%.Finally,subsequent field experiments demonstrated that utilizing this bionic digging tool for tea garden cultivation management led to a 30.6%reduction in resistance,indicating its superior effectiveness in reducing resistance.Furthermore,comparative analyses of tillage quality indicators such as tillage depth and tillage depth variation coefficient were carried out,it was found that this bionic digging tool not only reduced resistance but also exhibited high-quality performance in tea garden management.
