摘要:

以粤糖54-474甘蔗为试验对象,针对其甘蔗皮和甘蔗芯开展力学特性测试。在这些力学特性参数的基础上建立力学仿真模型,进行甘蔗切割的有限元分析与修正,并在此模型的基础上设计正交试验,对甘蔗收割机的刀具往复速度、工作速度、刀具夹角等参数进行优化。基于正交试验得到的优化参数,研制手扶式甘蔗收割机,并开展田间试验。结果表明:甘蔗破头率为6.9%,定向铺放率为91%,损失率为1.4%,初步达到了设计要求。

Abstract:

In the present study, the sugarcane variety Yuetang 54-474 was selected as the test object, and the mechanical properties parameters of sugarcane crusts and cores were determined. A special mechanical model of sugarcane was established based on these mechanical parameters, and finite element analysis and modification were carried out for sugarcane cutting. Based on this established model, orthogonal test was designed to optimize the working speed, tool reciprocating speed and tool angle for sugarcane harvester. Based on the parameters obtained from the orthogonal test, the hand-held sugarcane harvester was developed. The field test results of the prototype showed that the broken-root rate of sugarcane was 6.9%, the lodging rate in the special direction was 91%, and the loss rate was 1.4%, which all met the requirement in field.

Key words: sugarcane harvest, mechanical properties, simulation, orthogonal test
