Virtual design and virtual trial on cross-wedge rolling plastic deformation

The paper puts forward the overall idea of cross-wedge rolling plastic deformation trial based on virtual technology. It is intended to simplify the long obsessing design and trial on cross-wedge rolling plastic deformation. Built on the characteristics of cross-wedge rolling deforming process, virtual prototyping, neural network, CAD, Finite-element numerical simulation, Parameterization, Optimization and other relevant technologies are adopted in the virtual trial. An anticipant result of cross-wedge rolling trial is realized relatively perfectly. Meanwhile, a complete set of procedures such as equipment analysis, die design, part processing and strength analysis are fulfilled.
