Arguments put forth by the roller surface to approximate the mold surface, such as MARC's AUTOFORGE software using a B-spline surfaces. Beijing electromechanical the ongoing research work with natural surfaces and B-spline surfaces together describe the mold surface. This description method not only reduces the number of grids describing the mold surface, to reduce the time searching wheel contact, and make changes to eliminate the normal continuous contact locking phenomenon. On the grid and re-partitioning algorithm to generate finite element itself determine the characteristics of a great quality of deformable mesh impact on accuracy. Therefore, in the metal forming process simulation of the entire mesh quality should be maintained and will not be too bad. However, due to the diversity and complexity of the method of forging shapes, as well as metal forming large deformation characteristics, the researchers initial mesh generation and deformation of the workpiece during the distortion excessive redrawing the grid has become the field of finite element simulation of metal forming Another research focus wheel models, especially for three-dimensional bulk forming simulation problems, study the issue even more important, the greater the degree of difficulty. Most current volume forming simulation software using tetrahedral elements, characteristic of this unit is a cost-effective method of weight mesh generation and relatively simple to the complex shape of the boundary surface of coordination is good, but low accuracy. Therefore, the use of hexahedral meshes are efforts to target people. For this reason this issue on many years of research internationally wheel manufacturers, but has still not yet ripe. Currently there are several hexahedral mesh generation algorithms, such as cubes filling method, by the tetrahedral mesh into hexahedral mesh unit conversion method, and the solid surface layer by layer to generate internal entity law. Filling method can be automated and efficient, but the poor quality of the boundary unit on. Unit conversion method can be automated, the disadvantage is the poor quality of the mesh. A third method to generate the mesh quality is best, but because of the complexity of the generated mesh border coordination, so the internal point of each mesh point, the relationship between the surface and the surface is very complex, this approach to achieve great difficulty.
