【Abstract】 This article has discussed the theory model and the analysis method of the gantry device of the small sugar cane harvester.It has carried on the dynamic analysis to the gantry system.Through of the modality analysis and the forced vibration analysis,We obtained the primary vibration frequency and model of vibration which influenced the vibration.Through of the analysis to the model of vibration,we could propose that we should strengthen the gantry crossbeam,the rake wheel axle and the rigidity of the hydraulic cylinder.The establishment and the research of the virtual small sugarcane harvester have been consummated.更多还原
