Method of obtaining deformation information by tracing deformation from sections for 3D FE simulation

With the development of computer technology and finite element method, the priority research area of plastic forming has focused on the 3D FE simulation of forming processes for components with complicated geometrical shape. These processes have complex deforming mechanism, and different sections have different deforming characteristics. Therefore, for making a simple, convenient and practical analysis of its deforming law, how to obtain the deformation information of key sections from the results of 3D FE simulation has become one of problems urgently to be solved. So, a method of obtaining the deformation information by tracing the deformation from sections for 3D FE simulation has been proposed. From the deformation information got by this method, the deformation laws of key locations and the whole body can be obtained. This method can also help to compare the result from FE simulation with that from physical modeling. Key procedures of this method have been presented in detail, and it has been tested by applying it to the 3D FE simulation of precision forging of the blade with a damper platform. The result shows that the method is practicable and reliable, and it can also be applied to the 3D FE simulation of plastic forming processes of other components.
