Finite element modeling and comparative mechanical analysis of several hoeing tools

Abstract

Abstract To investigate the material selection basis of hoeing tools, the finite element software ANSYS Workbench was used to compare the material mechanical properties of several typical hoeing tools. Herein, ash wood (Fraxinus chinensis Roxb.), beech wood (Zelkova schneideriana Hand-Mazz), fir wood (Cunninghamia lanceolata (Lamb.) Hook.), oak wood (Cyclobalanopsis glauca (Thunb.) Oerst.), and locust wood (Sophora japonica (L.)) were selected for the hoe handles, and manganese 13 steel, type 45 steel, and spring steel were selected for the cutterhead. The corresponding finite element model was established by Solidworks software, and the force of the hoe tool under general working conditions was presented by ANSYS Workbench simulation, and then the dynamic performance of different materials was analyzed and compared by the comprehensive scoring method. The results of hoeing effect, hoe shank strength and cutter head strength show that the hoeing tool using spring steel as cutter head has higher strength, the hoeing tool using ash wood, beech wood, and Robinia wood as hoe shanks is better than that of zelkova wood and fir wood, and the choice of the material combination of "beech wood shanks + spring steel cutterhead" enables the hoeing tool to realize the best mechanical properties.
