| 摘 要： | 在采用离散元法分析玉米脱粒过程时,需要建立玉米果穗的分析模型。该文根据玉米果穗的结构和形态,提出基于颗粒聚合体的玉米果穗分析模型建模方法,并研制了玉米果穗的建模软件,同时添加到自主研制的玉米脱粒过程分析软件中。通过实际玉米果穗与其分析模型的对比和玉米脱粒过程的初步仿真分析,证明了该玉米果穗建模方法的可行性,为采用离散元法分析玉米的脱粒过程奠定了基础。

| Abstract: | It is necessary to establish the analysis models of corn ears to analyze corn threshing process using DEM(the Discrete Element Method).According to the shapes and the structure of corn ears,a method for establishing analysis models of corn ears based on particles agglomerate was proposed and the corn ears modeling software was developed,which was added to the corn threshing simulation software developed by our group.By comparing the corn ears’ entities with the analysis models and the simulation analysis of corn threshing process,the feasibility of the new method was validated.This paper provides reference for analyzing corn threshing process used by DEM. |
