| Abstract: | This paper adopts ANSYS software to analyze two kinds of blade of potato harvester. The finite element model is established for blade according to the position and material. The load is the resistance of soil to blade. It checks the blade intension by calculating the stress distribution and distortion. Optimal design which satisfies the harvesting requirement can be chosen from the analyzing result. It provides an academic basis for the design of blade. |
