Research on the Working Mechanism and Virtual Design for Cleaning Element in Brush Shape of the Sugarcane Harvester

摘要

The paper elaborated the working mechanism of cleaning element in brush shape of the sugarcanernharvester, and analyzed the state of cleaning procedure and the reacting force that the cleaning element wasrnsubjected. Combined with the earlier stage experiments and researches, it was found out that the factors, whichrnaffect the cleaning efficiency and fatigue life of cleaning element, were quite many, and the factors were complexrnand random. So it was difficult to analyze and design cleaning element in theory. Moreover, if the designrnparameters were got from experiment it would be time consuming, laborious, and costly. The method of numericalrnvalue simulation orthogonal experiment is used to analyze the reacting force by means of establishing finiternelement analysis model for cleaning element on ANSYS. According to orthogonal experiment principle, therndifferent parameter groups were made to do finite element calculation. And then orthogonal experiment analysisrnand regression analysis were made to find out the effect on the calculated result that was caused by the changes ofrndifferent parameter groups, and get optimal design parameters of cleaning element. In conclusion, this virtualrndesign method is a quick and efficient way in innovative mechanical product design.
