土壤采样器刃部结构优化设计有限元分析

Finite element analysis for optimum design of soil sampler edge structure

土壤采样是精准农业体系中的重要组成部分。设计了借助有限元软件ABAQUS建立了2种典型的能反映采样器刃部结构形式的土体模型,研究分析了土壤采样器压入对土体产生的扰动影响,土壤采样器结构对压入过程中土体单元的应变的影响,对提高采样质量、压入效率、优化土壤采样器设计具有实际意义。

Soil sampling is the important constitute part of exact agriculture system. In this paper, two typical models of stra- tum are built with software ABAQUS. It is researched that the disturb effective of soil sampling implement pressing into soil and strain influence of soil unit change made by soil sampling implement structure, which is very important for the soil quality and has the real meaning for optimization of the sampling implement design.
