Notice on Holding Special Training Course on Sheet Metal Stamping Technology
Related units: In recent years, with the rapid development of China's automobile industry and aerospace industry, the stamping industry has gained good development opportunities, but it is also facing severe challenges. The traditional sheet metal stamping method relies on experience and intuition, and adjusts many factors through trial and error in production, which has considerable randomness and uncertainty. In this way, it is difficult to shorten the product development cycle, reduce the cost and ensure the product quality. With the in-depth application of advanced manufacturing technology in enterprises, stamping technology has made unprecedented progress in depth and breadth, which is characterized by the combination with high technology and great changes in methods and systems. The infiltration and cross-integration of computer technology, information technology and modern measurement and control technology in the field of stamping has promoted the formation and development of advanced stamping technology. In order to meet the challenges brought by the fiercely competitive market to China's manufacturing industry, we should speed up the establishment of the product innovation and independent development system of domestic manufacturing enterprises, enhance the innovation ability and core competitiveness of product development, improve the rationality of product process design, and reduce the actual debugging times of molds, thus shortening the manufacturing cycle, reducing the cost of production debugging and improving the production efficiency of enterprises.

Professor Profile: Professor Liu Yuqi/Doctoral Supervisor. Mainly engaged in numerical simulation of metal forming, stamping process and die technology research. In September 2006, he went to WuMRC Advanced Manufacturing Center of University of Michigan in the United States to carry out technical cooperation as a senior visiting scholar. He has published more than 50 academic papers, including 5 articles retrieved by SCI/KLOC-0 and 9 articles retrieved by EI. He presided over the completion of the Ninth Five-Year Plan 1 Key Research Project (1996- 1998), Jilin Natural Fund 1 Project (2000-2002) and Ministry of Education 1 Key Project (2002-2004) He presided over the National Natural Fund Project 1(2006-2008) and the National "863" Project 1(2007-2009). As a major participant, he participated in two key projects of National Natural Fund and 1 Tenth Five-Year Plan. A commercial numerical simulation software FASTAMP is developed, which includes the explicit incremental method of sheet metal forming force and the solver of finite element inverse algorithm. The preprocessing has international advanced CAD data conversion interface and finite element mesh splitter. As a commercial software, it has been widely used in 10 automobile groups and mold companies, bringing great economic and social benefits. Brief introduction of achievements: The sheet metal rapid prototyping simulation software FASTAMP with completely independent copyright has been developed. The software has inverse algorithm solver and explicit incremental algorithm solver, and has a complete pre-and post-processing system, including CAD data interface with high compatibility, surface mesh splitter with good quality and speed, and rich point/line/surface/element editing functions.
