Design and Optimization of Honeycomb Corrugated Chaff Forming Roller

By analyzing the material properties and forming characteristics of the 0.8mm length side hexagon honeycomb corrugated chaff , we studied forming roller’s design and optimization while making corrugated chaffs used forming method and focus on the influence of the chamfer of teeth top edge and number of teeth to forming quality at the corrugated chaff corner .We used finite element analysis software ANSYS / LS-DYNA to simulate the forming process of corrugated chaff , studied the stress contour and stress-time curve of typical element, found the optimal chamfer of teeth top edge and number of teeth, then we used the designed forming roller to verify the effect of chaff forming . By comparison experimental and simulation results,we found good agreement between the two, when the chamfer of teeth top edge dj = 0.08mm, number of teeth z = 40, the chaff has the best forming quality .
