Numerical Simulation of Precision Forming for Blade Rotor Based on DEFORM
In order to study the deformation characteristics of the blade rotor in the precision forming, by means of the plastic forming software DEFORM-3D, the forming process is simulated. It is concluded that (1) the change of the stress and strain in different stages was simulated during the entire forming process. (2) Based on the stress and strain distributions, the analysis of the metal flow rule and the mechanism of the filling mold was proceeded to find that the properties of the blade rotor can be enhanced by means of the precision forming.
