3D Solid Model Establishment and Finite Element Analysis of Corn Seed

摘要

In order to study the inner mechanical damage mechanism of corn seed, a new method of establishment of corn seed 3D solid model is proposed in this study: corn seed section images are collected; image cropping and size proportion restoration are finished by Photoshop; actual size of corn seed is reduced and outline of the different composition is extracted in AutoCAD; and the corn seed 3D solid model is established in Solidworks with the extracted outlines; then the 3D solid model is divided into solid meshes to establish finite element model; static load analysis is carried out on the finite element model and diagram of corn seed inner stress distribution is given.
