曲轴的参数化有限元分析

In the analysis that the main force and the major damage way of the crankshaft the premise, the mathematical model is built with finite element, the loads and the constraints are applied virtually. Using the finite element analysis software, ANSYS, parameterization analysis is carried out for the Crankshaft. We analyzed the maximum tensile stress, the maximum shear stress and stress distribution map of the Crankshaft, found the easily damaged points, except that we summarized the equation that the change of the tensile stress follow up the size of the Crankshaft. All of the analyses provide the theoretical basis for protection and improvement of the Crankshaft.
