摘要
以海南省临高县青皮甘蔗为对象,利用WD-200B型电子式万能试验机对青皮甘蔗节点进行了切割力学试验研究。试验结果表明,同一加载速度250 mm/min下,甘蔗节点的切割力呈现从中部、根部、梢部、尾部逐渐减小的趋势;同一部位下,甘蔗节点的切割力随着加载速度的增大稍有波动。以加载速度、加载部位直径作为试验影响因素,采用正交试验方法分析各因素对甘蔗节点切割力的影响。结果表明,各因素对甘蔗节点切割力的影响为加载部位直径>加载速度。在加载速度为100 mm/min,粗直径的甘蔗节点的切割力最小。
The green-skinned sugarcane from Lingao county in Hainan province was used as the test material.The cutting characteristics of the nodes of the green-skinned sugarcane was studied on the WD-200B electronic universal testing machine.Results showed that cutting force of sugarcane nodes decreased gradually along with the roots,central,tip and the tail under the same loading speed of 250 mm/min.Cutting force of the sugarcane nodes affected slightly with the increase of loading velocity under the same parts.Factors such as loading speed and loading parts diameter on sugarcane cutting force were analyzed with orthogonal test.Factors affecting the cutting force of sugarcane node were in order of loading parts diameter ＞ loading speed.Cutting force of sugarcane node with thicker diameter was found to be the minimum when loading speed was 100 mm/min.
