An Overview of the Finite Element Method on the Tool-Soil Interacting Problem of Tillage

摘要: This article introduced the up-to-date research progress on tool-soil interacting problem of tillage; and investigated situation constitutive relation usage in finite element method (FEM). A review including dynamic effect performance tillage operation with FEM has been conducted. It showed that virtual reality had made much evaluating tool draft, distribution position stress strain, displacement fields acceleration soil-tool interactions, soft ware package computer aided design tools; it will be a low cost high efficiency assistive development procedure tools, can applied to study analyze resulting prototypes.
