In order to explore the impact of the process parameters in the necking process of titanium alloy self-locking nuts on the forming law of the necking area,this paper establishes the finite element simulation model of the necking process of titanium alloy TC4 self-locking nuts based on ABAQUS,carries out the secondary development of ABAQUS to realize the parameterization of the pretreatment process,and builds the GUI interface,so as to effectively reduce the time and effort required in establishing the finite element simulation model of the necking process for the efficiency improvement of the finite element simulation.Plug-in is applied for simulation research.The results show that increasing the closing amount and the height of the closing point can significantly improve the deformation of self-locking nut.
