Material Analysis and Structural Study on Powering Divider of Herbage Harvester

摘要

In order to study stress deformation and distribution of powering divider on 4GH-120 herbage harvester at working time, main materials of the divider were analyzed, and mechanical model of the divider was established by finite element method. Result showed that maximal displacement deformation and stress distribution appeared on the left tooth of divider; stress value decreased from center to edge; Choosing 6 mm tooth thickness and 430r/min rotating speed was the best effect, deformation displacement and equivalent stress are respectively reduced by 53.5% and 54.2% compared with original dates. In 320～400 mm diameter scope, the smaller the divider is, the safer it is.
