Secondary Development of Finite Element Simulation Program and Experimental Verification of Multi-step Continuous Forging
For long-shaft heavy forgings,multiple forging passes and several blows per pass are involved,the forging billet is fed at a certain distance after per blow and is rotated a certain angle after per pass,so the forging process is very time-consuming.The numerical simulation has become one kind of the most effective methods to study the forming process of heavy forgings.Presently,the simulation of the forging process of heavy forgings is mainly based on the multi-step simple forming process modeling,the influences between each pass are usually ignored.The function call module in text mode based on DEOFRM-3D software was developed to realize the simulation of multi-step continuous forming process of heavy forgings,therefore,the numerical simulation model is in line with reality.The whole multi-step continuous forging process was simulated based on the developed finite element simulation program,the surface temperature and dimension variation of forgings were obtained,and the corresponding experiments were carried out.It shows that the simulation results conform well to the experimental one.It indicates that the developed finite element simulation program can be used to simulate the multi-step continuous forging effectively.
