摘要
为探究钛合金自锁螺母收口工艺参数对收口区域成型规律的影响,基于ABAQUS建立钛合金TC4自锁螺母收口成型过程的有限元仿真模型,对ABAQUS进行二次开发以实现前处理过程的参数化,建立GUI界面从而有效减少收口过程有限元仿真模型建立所需的时间与精力,提高有限元仿真效率。仿真研究结果表明:增大收口量与收口点高度能够显著提高自锁螺母变形程度,从而提升产品的锁紧性能。
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.
