基于ANSYS/LS-DYNA的实体膨胀管膨胀力分析

Analysis on Deformation Force of Solid Expandable Tubular Based on ANSYS/LS-DYNA

应用非线性有限元分析技术,利用ANSYS软件的LS-DYNA模块动态模拟了膨胀套管的全过程,得到了膨胀力随时间变化的曲线,并分析了在不同的工艺参数(膨胀锥角、摩擦因数、膨胀速度)下的膨胀力变化情况,得出了膨胀参数与膨胀力的关系,为膨胀工具的设计及膨胀方案的优化提供了依据。

2D axial symmetry non-linear FEA technique was used to simulate the whole process of expandable tubular dynamically based on ANSYS/LS-DYNA module of ANSYS. The relations of deformation force and processing parameters were achieved. Thus Foundation was laid for optimal design of expandable tool and technological design of expandable tubular.
