Abstract: In order to improve the performance of the sugarcane cutting tool, the effect of different tool angles and cutting speeds on cutting force and broken rate should be studied. The simulation of the sugarcane cutting process based on ANSYS/LS-DYNA was carried out in this paper. Different finite element models consisting of different tool angles and cutting speeds were built. The MAT_WOOD material model and contact erosion arithmetic provided by LS-DYNA were used in the numerical analysis. Simulation result showed that the effect of cutting speed on cutting force energy consumption and max stress of the tool was significant; and the effect of different tool angles on cutting force was significant, and the minimum cutting force was gained when the tool angle was zero. The slower the cutting speed was, the smaller cutting force was as the cutting speed range form 0.5 to 0.9 m/s. The comparison between the experiment result and simulation result showed that effect of different speeds on the cutting force had the same trend. Relative error of the maximum cutting force was less than 20%. The finite element simulation of the sugarcane cutting can reduce the cost and time consumption of the experiment and provide reference for the design of prototype.
