Fracture failure analysis and structural optimization of cylinder shaft of combine harvester based on ANSYS Workbench
The strong threshing ability and high working efficiency of tangential longitudinal axial-flow grain combine harvester are the development trends of the future harvesting industry.During the operation of the combine harvester,due to the unstable feeding amount and the uneven material layer,the tangential flow threshing cylinder was subjected to a large impact of alternating load,resulting in the failure of the cylinder shaft.The static and fatigue life of the roller shaft were analyzed by using ANSYS Workbench software,and the reason for its fracture failure was found to be fatigue fracture.On this basis,the structure and materials of the shaft were improved,the maximum stress of the improved shaft was reduced to about 40.6% of the original value,and the reliability of the improved shaft was verified to ensure safe harvesting operation.
