论文摘要
确定甘蔗单键坯的物理和机械性能是甘蔗种植园机械结构设计的关键步骤。在这项研究中，分析了Taitang F66品种甘蔗样品。钢坯的水分含量范围从63.78％到77.72％，平均密度为244.67 kg/m3。样品的恢复系数（COR）是通过进行液滴测试来确定样品从不同高度滴入钢板上的。四种样品的静态摩擦系数（SFC）由两个方向的倾斜板法确定。另外，在三个板倾斜角和样品位移下确定滚动摩擦系数（RFC）。实验结果表明，随着跌落高度和水分含量的增加，钢坯钢COR从0.625降低到0.458，而钢坯钢芯从0.603升至0.698。随着接触面积的增加，钢坯钢SFC从0.515降低到0.377，而钢坯钢筋SFC从0.498降低到0.323。随着角度和样品位移的增加，钢坯钢RFC从0.0315增加到0.2175，而钢坯RFC从0.0203增加到0.1007。这些参数可用于使用EDEM模拟的甘蔗单个坯料花盆的设计和优化。
Determining the physical and mechanical properties of sugarcane single-bud billets is a critical step in the mechanical structure design of a sugarcane planter. In this study, the TaiTang F66 cultivar sugarcane samples are analyzed. The moisture content of the billets is found to range from 63.78% to 77.72%, and the average density is 244.67 kg/m3. The coefficient of restitution (CoR) of the samples is determined by conducting a drop test wherein the samples are dropped onto a steel plate from different heights. The static friction coefficient (SFC) of four types of samples is determined by the inclined plate method at two orientations. In addition, the rolling friction coefficient (RFC) is determined at three plate inclination angles and sample displacement. The experiment results show that with increasing drop height and moisture content, the billet steel CoR decreases from 0.625 to 0.458, while the billet billet CoR increases from 0.603 to 0.698. With an increase in contact area, the billet steel SFC decreases from 0.515 to 0.377 and the billet billet SFC decreases from 0.498 to 0.323. With increasing angle and sample displacement, the billet steel RFC increases from 0.0315 to 0.2175 and the billet billet RFC increases from 0.0203 to 0.1007. These parameters are useful in the design and optimization of sugarcane single-bud billet planters using EDEM simulation.
