ABSTRACT:The aim of the study was to design a process of forming double-hole shells and manufacturing qualified prod-ucts. By numerically simulating the forming process of double-hole shells, the forming tendency, strain and stress diagrams were analyzed to provide a theoretical support for the process design. The viability and rationality of double-hole shells ex-trusion process were optimized and verified by simulation and calculation. In conclusion, by process scheme analysis and finite element simulation and calculation, the final scheme for forming of double-hole shells was confirmed, and qualified products were manufactured.
