Three-dimensional FEM analysis for a kind of engine crankshaft

By using SolidWorks2010 software 3d entity modeling for the engine crankshaft of the developed tobacco harvest machine was built, and Ansys system combining working conditions to crankshaft with Ansys finite element method was imported. Then the crankshaft's stress result figure in four conditions was got, the stress concentration area was found, comparing and the analysis the the working conditions of the results, thus the basis theory for the engine of the crankshaft structure optimization design and research was provided.
