| Abstract: | Qualittive physical simulation is used to test the stress state of axis line of the forge piece by using FM -UL- V forging,and it follows that when W/D equals to 0. 34,the center of the forging piece is in the three-dimensional pressure state. It is corresponding to the result of the quantitative experiment of simulation. Simultaneously,this paper also provides a novel,easy, reliable and applicable test method for quantitative simulation and numerical calculation. |
