| Abstract: | The internal high pressure forming (IHF) technology that can be applied in the fields of aerospace and automobile etc has many advantages such as lightweight of parts, high rigidity, less components needed, amount of succeeding machining and welding assembling are reduced greatly, and low cost etc. By means of numerical simulation, the proper flow trend of material and the effect of material flow on the finished workpieces during IHF are analyzed. Some comparison between simulation and experiment are studied. It is shows that it is very important to control formation and shape of wrinkling by means of applying the optimized process parameters during IHF of low plasticity material. |
