  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.
