| Abstract: | The technology of numerical simulation has been regarded as an aided tool in modern manufacturing industry, which adopts the virtual manufacturing technology to actually reflect the interaction between the mould and blank, and it is playing more and more important role in fast manufacturing and intellectualized design. This paper presents a numerical simulation technology to a multi-stage metal drawing process, which brings a practical application, and uses the numerical results worked out by finite element software LS-DYNA to analyze the law of metal flowing in the drawing process, etc. |
