Abstract

In recent years, with the development of computer technology, domestic and foreign scholars and metal forming production researchers, began to use computers for metal forming production of quantitative research, in which the finite element method is the most successful. At present, the international enterprises in many developed countries have been using computer simulation technology to the metal forming design and production of enterprise production and improve competitiveness has played a significant role in promoting. The United States, for example, the United States research institutions and large enterprises since the 20th century, 70 years has invested a lot of manpower and resources to carry out research and development in this area has been successfully developed a number of sets of commercial finite element software to achieve metal forming finite element simulation , Including volume forming and sheet metal forming, many companies are widely used in the production of this technology. However, the commonly used static implicit finite element method has many difficulties in actual stamping production, such as long calculation time, the processing of contact problems often cause the calculation of divergence, especially when solving three-dimensional problems more difficult to solve, affecting many practical Simulation of Stamping Process.
