This paper introduces the structure and picking principle of picking device on the roller stripping -type cotton harvester , the 3D model of cotton-beated roller was established , using the 3D modeling software Pro/E.The modal anal-ysis for cotton-beated roller was carried out by using the finite element analysis software ANSYS Workbench and acquire the natural frequencies and modes of vibration .These results provide a theoretical basis to avoid the resonance region and structural optimization design;transient dynamic analysis was made on the longitudinal cotton bat in order to calculate the rule of stress field , find out the regularities of distribution , it can provide theoretical reference for the improvement of picking part .
