Abstract

In this paper, the basic rigid unit and discrete element rigid model of reed stem and discrete element flexible model of reed stem were established by means of multi-spherical filling and other methods. Then, three-point bending test was carried out in EDEM software to complete the calibration of bonding parameters. Finally, simulation analysis was carried out with the loss rate as the index. The simulation results show that the optimal parameter combination is 46 r/min for the transverse transmission device, 53 r/min for the vertical clamping longitudinal transmission device, and 470 mm for the center distance of the drum. Finally, the initial field test verifies that the maximum parameter combination of the harvester header is 49 r/min for the transverse conveying device of the header, 51 r/min for the vertical clamping longitudinal conveyor and 1.1 m/s for the field forward speed of the reed harvester, and the loss rate of the harvester is 3.36%, and the optimal parameter combination is consistent with the simulation analysis results.
