| 摘 要： | 为了使膨胀管的膨胀过程顺利进行,研究了膨胀锥锥角、膨胀锥与膨胀管之间的摩擦因数等参数对壁厚减薄量、轴向长度收缩量和膨胀力的影响,并优化了膨胀参数.在参数优化的基础上,利用ANSYS有限元分析软件对X52膨胀管的实际膨胀过程进行了模拟,结果表明:膨胀管膨胀后壁厚变薄,轴向长度收缩;轴向和环向的残余应力较大,其他方向的残余应力较小;膨胀力随着膨胀过程的进行呈现一定的变化规律.通过试验结果和模拟结果的比较,验证了模拟的合理性.

| Abstract: | To lead a successful expansion,the effects of expansion cone and friction coefficient on the reduction ratio of tubular wall thickness,the axial length contraction and deformation force were investigated,and the corresponding parameters were optimized.The expansion process of X52 expandable tubular was simulated by ANSYS FEM software according to the optimized parameters.The simulation shows that after expansion,the wall thickness gets thinner and the axial length contracts;the axial and circumferential residual stress becomes larger than that in other directions.The deformation force varies with the expansion with a certain trend.The simulation is verified by the experiments. |
