摘要
快速充液成形是一种利用高能液体的冲击进行零件弹塑性成形的先进成形技术。由于在短时间内可以提供较高的成形压力及能量,因而可以方便地成形局部变形大的零件,有效地降低设备的吨位。本文基于已完成的厚壁管坯零件的快速充液成形实验,利用有限元软件ANSYS/LS-DYNA对此过程进行了数值模拟,数值模拟结果与实验结果基本一致,根据数值模拟结果分析了管坯的变形过程,给出了位移的变化曲线和管坯壁厚的变化曲线,为进一步优化工艺提供了基础。
Rapid hydraulic forming is an advanced forming technology that the impact of high-energy liquid is used to ac complish elastic-plastic forming of metal parts. Since this method can provide high forming pressure and energy in a short time, parts with big local deformation can be formed conveniently, thus the tonnage of equipment can be reduced. Based on the completed rapid hydraulic forming experiments of thick walled tube, numerical simulations for the process were done by using finite element software ANSYS/LS-DYNA, and the results of numerical simulation and experiments were basically consistent. At the same time, the tube deformation process was analyzed according to the numerical simulation results, the displacement curve and the tube wall thickness curve were also plotted, and the humerical simulation results provide a basis for further process optimization.
