Elastoplastic finite element analysis of assembly process of hub bearing assembly
The assembling process of the hub bearing assembly and the rotary forging process using the three-dimensional elastoplastic finite element analysis function was carried out. The bearing was assumed to be an elastic body. Above figure shows the residual stress.

Read MoreNew grip model
Recently a grip model for roll forging was improved. With the new grip model, we can apply pulling force to the material, which is proportional to the roll separating force. Of course, The maximum pulling force by some limited value given by users can be constrained. With this model, more stable and accurate predictions could…
