| Abstract | The preform billet shape of the 7050 aluminum alloy giant plane forgings has been designed using electric field method based on similarity principle. Firstly, the electrostatic field was analysed by using ANSYS software, from which the preform billet shape was obtained based on electrostatic field equipotential lines. The preform shape, press velocity, temperature and friction factor were taken as parameter variables, while the forming load, filling rate and grain size were chosen as optimization goals. The mathematical model was optimized by the use of a Model-Based Calibration (MBC) toolbox for modelling, Three-Dimensional of Design Environment for FORMing (DEFORM-3D) for simulation and CAlibration GEneration (CAGE) toolbox, obtaining the best preform shape and the optimal combination of process parameters (friction factor μ = 0.2, press velocity ν = 9.8 mm/s and billet temperature T = 478 °C) when the equipotential line was ξ = 0.425 V. Finally, comparing with initial preform shape, the results indicate that the optimized preform billet designed by electric field method has an advantage in finish forging, while the forming load of finish forging reduces by about 38 % and the average micrograin size reduces by about 45 %. Therefore, it provides an effective method for designing preform billet shape of complex forgings. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
