Abstract:In order toinvestigatetheeffectof cuttermovementonsugarcaneharvestingquality andimprovethecutting
qualityꎬthis paper studied the kinematics law of double base cutter in sugarcane harvesterꎬand calculated aformula
to describe thekinematicslaw.Thebestmotionparametersꎬforwardvelocityof harvesterꎬspeedof cutterrotationand
numbers of blades couldbecalculatedthroughthisformulatocontroltherepeatedcuttingtimes.Toverifythevalidity
of theformulaꎬa three ̄dimensional entity model of the sugarcane cutter was built using pro/ E. The motion of the
model wassimulatedusingAdamsꎬandthedisplacementcurveandtrackdiagramofthepointsof bladeswasobtained
based on the simulation results. The results showed that the repeated cutting frequency of sugarcane would increase
with the increase of coefficient P in the formula under the condition of different forward velocity of harvester and
