Abstract

The parameters of cassava mechanical properties are very important for the design, dynamic simulation and mathematical model of cassava harvester. In order to study the cassava stalks cutting force, stress, power indicators influencing factors, using WD-200B computer-controlled electronic universal testing machine, orthogonal experiments are conducted to test the cassava stalks cutting force, cutting angle is selected, cutting speed, and cassava cutting parts diameter as the impact factors, results of the research show that when the cutting angle is 60 °and the cutting speed is 250mm/min, roots as the cutting site, the diameter in the coarse time, the required cutting force, cutting stress and power reach the maximum capacity.For the same cutting speed case, the cutting force of the middle is the maximum, the root is the next, the cutting force of the tip is the minimum; the stress of central part is the maximum, the root is the next, the smallest is tip stress; the middle has the maximum power, the root is the next, followed by tip power. For the same parts of the stalks, with the thinner diameter from coarse cutting force decreased; gradual decline of power; unrelated stress magnitude and diameter size have nothing to do with the stalks parts in 2.5MPa fluctuate. With the angle changes, the cutting Force, stress, and power of the tip portion ate significantly lower than the central and root. The study results provide a theoretical basis for grinding cassava stalks harvester developed.
