Abstract

Axial cutter vibration has a negative effect on the cutting quality of sugarcane harvesters. Axial cutter vibration displacement-measuring experiments without cutting sugarcane were performed in two lifting hydraulic cylinder installation positions on a self-developed sugarcane harvester experiment platform (SHEP). This experimental investigation consisted of single-factor and orthogonal experiments to be prepared for further sugarcane-cutting experiments conducted on the SHEP. The effects of the sugarcane field excitation, the engine excitation, the cutter rotation velocity, and the lifting hydraulic cylinder installation position on the axial no-load cutter vibration were studied. The sugarcane field excitation and the engine excitation had significant monotonic positive correlated effects on the axial no-load cutter vibration, while the cutter rotation velocity had a significant monotonic negative correlated effect on the axial no-load cutter vibration. The sugarcane field excitation, the engine excitation, the cutter rotation velocity, their interactions, and the lifting hydraulic cylinder installation position all had significant effects on the axial no-load cutter vibration. The significance levels from high to low were as follows: the lifting hydraulic cylinder installation position, the sugarcane field excitation, the cutter rotation velocity, and the engine excitation. Suitable experimental factor values and the suitable lifting hydraulic cylinder installation position were obtained for further sugarcane-cutting experiments. Suitable values for the cutter rotation velocity and input frequencies of the simulated sugarcane field exciter and the actuating engine were 700 r/min, 22, and 22 Hz, respectively. The lifting hydraulic cylinder of sugarcane harvesters should be installed in the front of the cutter frame, near the cutter.
