Virtual Experimental Analysis On The Cleaning Element In Brush Shape Of The Sugarcane Harvester

Sugarcane is the major economical crop in the south of China, and is mainly cropped at hill, and sloping fields. Because a great majority of sugarcanes are winding and lodging, they make it difficult in harvesting mechanization. Sugarcane cleaner is one of the major parts of the whole-stall sugarcane harvester. The cleaning element is subjected periodical stress on its' root in the working procedure, and then is apt to fatigue broken. And the fatigue life of cleaning element is the bottleneck to the popular application of sugarcane cleaner. Therefore it has great important practical significance to design a new type of cleaning element with high sufficiency and long fatigue life.In this paper, it was carried out a virtual experimental analysis on cleaning element with the method of numerical value simulation orthogonal experiment. The mechanical properties of three engineering materials were got through performance test to control the quality of the materials. The influence law on the cleaning efficiency of different installation of the cleaning element can be got through dynamic and static experiment, and the research on the mechanism of cleaning element. After that, according to the principle of numerical value simulation orthogonal experiment, this paper was conducted a virtualiiorthogonal experiment with standard orthogonal table on the FEA software-ANSYS to get the optimal combination of different level of different factors, which affect the efficiency of cleaning leaf. And the virtual experimental results were analyzed with variance and regression analysis to proceed the test of significance and reveal the inherent relationship between the cleaning efficiency and factors with equation of experience. Based on the principle of least square method, one available curve of S-N was conducted curve fitting, so the experience equation of the curve can be taken to forecast the fatigue life of the cleaning element that is made up of the optimal combination of different level of factors. Therefore it can provide reference materials to select reasonable cleaning element. In order to provide a quick and convenient tool with the seriation study of cleaning element, each analysis section was also sealed up and integrated on the virtual experiment platform based on VB (Visual Basic) software and APDL (ANSYS Parametric Design Language) of ANSYS. Practice and experimental results show that virtual experimental analysis not only economizes time, material and human resources, but also is an effective way to solve multi-factors experiment.
