Simulation and Experimental Study on Sugarcane Field Excitation to the Cutter

The Sugarcane field excitation has notable influence on the sugarcane cutting quality, but its mechanism has seldom been studied. Based on the dynamic model analysis, this paper measure, analysis and test how the field excitation impacts the vibration of the cutter. After building up 3D model of the vehicle and field system, virtual simulation analysis on it is carried out, deducing that the frequency of field unevenness has notable influence on the vibration of the cutter. In physical experiment, it compares and analyzes the vibration of the cutter and cutting quality under different frequencies of field unevenness. The result shows that, the frequency of field unevenness has magnificent influence on the vibration of the cutter, and the higher the frequency the more deteriorated the sugarcane cutting quality.

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.
