Simulation of Effect of Knife Rollers Rotation Modes on Wind Field

摘要

In order to study the influence of different knife rollers rotation modes for the wind field inside the diversion cover of the sugarcane leaf cutting and returning to field machine equipped with flexible cutters, the ALE method of finite element software LS-DYNA was applied to operate the simulation of wind-field fluid-structure interaction inside the diversion cover, which was under the condition of two knife rollers in clockwise rotation and the clockwise rotation of the master knife roller and the anticlockwise rotation of the slave knife roller respectively. According to the comparison of the simulation results, under the condition of two knife rollers in clockwise rotation, the wind field inside the diversion cover was more stable, which would decrease the influence of the wind field on the process of cutting the sugarcane leaves and benefit the output of the sugarcane leaves.
