Optimization Research on the Working Parameters of Sugarcane Harvester on the Cutting Time of Stalks Using Virtual Prototype Technology

This research established a virtual prototype of the sugarcane cutting system. The influence of the harvester on the cutting time of sugarcane stalks under the conditions of different forward speeds and cutting disc speed was studied. Using a dual variance analysis of the experimental data, it was revealed that the rotating speed and forward speed of the cutter disc of the sugarcane cutter had a significant influence on the cutting time. The empirical regression equations between the cutter spin speed- n of the sugarcane cutting device, the forward speed- v of the harvester, and the cutting time- T are given, that is, T= 12.38-0.5875v-0.0137n . Further analysis of repeated cutting and missing cutting during the cutting process was conducted. The result revealed that the optimized cutting disc speed range value was as follows: 423–579 rpm, and the optimal forward speed range value is as follows: 0.66–3.07 m/s.
