| Sumario: | Aiming at the problem that when the finite element software is used to analyze the influence of multi parameter changes on the research object,it is necessary to repeatedly model,define and modify parameters,an improved programming method and graphical user interface establishment method were provided.Taking the dynamic shear extrusion connection of intermediate billet as an example,the python language was used for secondary development of ABAQUS pretreatment,and the kernel script of dynamic shear extrusion connection simulation was programmed.Then the graphic user interface of dynamic shear extrusion connection was established by using RSG plug-in.Finally,simulation analysis was conducted.The results show that users can input different process parameters,die parameters and blank parameters according to the actual situation to complete the pre-processing operation automatically,which not only effectively solves the problems of complicated and error prone model assembly,but also improves the accuracy of model assembly and simulation results,so the feasibility of the secondary development program and graphical user interface is verified.The study provides a powerful tool for the follow-up study of the influence of different reduction,overlap,edge width and other parameters on the dynamic shear connection quality of intermediate billet,and provides a reference for the secondary development of ABAQUS in other fields. |
