In order to solve the problem of thermal-force-gas multi-physics integrated control in superplastic forming process and improve the forming quality,production efficiency and product consistency of lightweight multi-layer complex structural parts,a digital twin system was developed by the integration of information technology with material,process and equipment.Then,the key technologies such as physical model of superplastic forming production unit,digital twin modeling based on process flow,multi-source heterogeneous data col-lection and storage based on edge gateways,process database and data visualization were studied.Furthermore,the experimental verifica-tion was carried out on the independently developed 8000 kN superplastic forming/diffusion joining equipment,and the entire process of TC4 titanium alloy hemispherical forming was completed,achieving visual monitoring and control of the superplastic forming equipment and process,which provided ways and methods to realize the digitization,automation and intelligence of superplastic forming process.
