| Abstract: | The forging process is simulated using flexile-plastic finite element software MSC MARC/AUTOFORGE based on the optimal strain rate.For the different materials,friction coefficient,working temperature,different forging times and length,the total equivalent plastic strain,biggest forging force and increasing degree of diameter for the work piece are studied.And then the effects of these factors on cylinder semi-finished product forming,forming precision and deformation law are discussed.At last an important forging procedure is worked out,which plays a guiding role in forging forming and die designing. |
