The Crankshaft Parametrical Model Technique And Intensity And Study Of Residual Deforming In Rolling

The thesis has done intensively research about problems of the techniques of crankshaft parametric 3D integer model, the analysis of crankshaft strength, the model analysis and residual deforming in crankshaft rolling process.It puts forward design schemes and steps of 3D parametric crankshaft model by applying the finite element analysis (FEA) .It applies APDL to program the analytical integral module of different types of parametric crankshaft. It uses Visual C++ 6.0 to develop the friendly man-machine conversation interface and encapsulate ANSYS. So automation of parametric 3D integer model, analysis and calculating is achieved.Considering comprehensively the complicated work conditions and making use of the above-mentioned crankshaft paramedical model techniques, by taking the 480Q crankshaft as an example, the thesis carries out crankshaft static intensity analysis that has logical model and high precision and crankshaft dynamic characteristic analysis of torsional vibration, flexural vibration, longitudinal vibration, amplitude and so on.It has developed the parametric residual deforming FEA in crankshaft rolling process. At the same time, by using of crankshaft model techniques not only enable crankshaft to set up the model automatically, but also calculate and analyze its physical volume, center of gravity, the position of rolling and the size of rolling pressure, etc. The residual axial and bending deforming in crankshaft rolling process is predicted, the relation between rolling load and whole deforming is also studied, thus this paper make the technical personnel and engineering directly analyze the residual deforming in crankshaft rolling through the system, in order to adjust crankshaft after rolling and alleviate the workload greatly. Fatigue strength of the 480Q crankshaft is checked and the result indicates that the crankshaft can reach intensity demand after boosting.
