The application of finite element simulation technology in aerospace plastic forming field was systematically explored,focusing on the analysis of plastic forming simulation process,practical application cases and future development trends.In response to the current situation where the application objects of finite element simulation technology in the aerospace field were limited to the theoretical level of materials and processes,the effectiveness of simulation technology in predicting stress and strain distribution and workpiece geometric shape changes was verified through practical engineering cases such as TA15 cylinder hot spinning,5A06 aluminum alloy skin hot pressing forming and TC4 titanium alloy hot pressing/superplastic composite forming.The research results indicate that compared with traditional physical experiments,the finite element analysis technology can significantly reduce the frequency of experiments,accelerate the prototyping process,reduce manufacturing costs and greatly increase the scale of effective data.At the same time,facing the current situation of lagging digital development in the plastic forming field of domestic aerospace manufacturing industry,the future development trends of multi-scale simulation technology,process full-process collaborative simulation,simulation data and process management,and the intelligent construction of process design and manufacturing were discussed.The key technical solutions for the digital and intelligent development of plastic forming technology were proposed.Finally,the importance of simulation technology in aerospace plastic forming was summarized and suggestions for future research directions were also provided.
