Simulation Analysis and Experimental Study on Rigidity Enhancement of Sugarcane Harvester Cutter

The rigidity of sugarcane cutter has notable influence on the quality of sugarcane cutting,the most concerned problem of sugarcane harvester developing currently,as it effects its vibration and the vibration in turn brings great damage to the cutting quality on which rare research has been done. This paper took altering a sensitive parameter of the cutter rigidity, the distance between the bears of the shaft as a case to investigate how the enhancement of the cutter rigidity brought the improvement of the cutting quality by applying ADAMS program to perform dynamic simulation of the cutting process after designing their 3D models in Pro/Engineering and making ANSYS analysis of the according effects. Further, a physical experiment following showed that proper design of the distance between the cutter shaft bearings that enhancing 23.67% of its rigidity could lead to 29.20% improvement of the sugarcane cutting quality.

Virtual Simulation Analysis and Experiment Study on a New Peel Scratch Relieving Design of Sugarcane Leaf Cleaning Device

Relieving peel-scratch without raising the remnant leaf rate is the bottleneck in further perfecting the key component of the small-sized sugarcane harvester, the cleaning device. Therefore, to solve this dilemma, a new arrangement design of cleaning elements of sugarcane leaf cleaning device is proposed based on the cleaning mechanism analysis. To obtain the crucial effecting parameters and evaluate the motion and dynamic function of this design quickly and efficiently, virtue prototype technology is applied to build up a three-dimension model and perform a simulation analysis on the automatic dynamic analysis of mechanical system (ADAMS).Thereafter, a comparison experiment study between the new arrangement and the old ones ensued, confirming the previous analysis that the new arrangement design of cleaning elements do significantly relieve sugarcane peel scratch 10%~28% and still maintain satisfying cleaning effect. This provides reference to tackle the design dilemma in such a quick and efficient way.
