摘要
论述了马铃薯挖掘机关键部件挖掘铲的设计方法,并基于土壤与铲体作用力学分析建立了挖掘铲牵引阻力数学模型,最终确定了挖掘铲设计参数。同时,详细地阐述了基于CATIA的挖掘铲三维参数化建模的基本方法。
The principal parts design of potato harvester and the determination of parameters were stated in this article. The draught resistance mathematic model was set up based on dynamics analysis of digging blade and soil. At last the design parameters of digging blade were confirmed. At the same time, a study is carried out upon three-dimensional parametric modeling method and its technology based on CATIA, the basic method anti general steps of potato digging blade 3-D parametric modeling are expounded in detail.
