| 摘 要： | 基于弹性力学理论,提出了一种组合材料的连续油管注入头夹块结构。利用ABAQUS对比分析了常规和组合材料夹块在相同条件下的接触压力分布规律,并对组合材料夹块结构的端面倒圆角半径、环向倒圆角半径进行了优选。分析表明:组合材料夹块结构更加有效地将夹持力传递给连续油管,使得连续油管的接触压力提高且分布均匀,有效地提高了夹持的可靠性。

| Abstract: | Based on the elasticity theory,a composite material clamping structure was constructed.By using ABAQUS,the contact stress distribution between conventional and new combined were comparatively analyzed in the same condition,the end face fillet radius and circumferential fillet radius of new combined material block were optimized.The analytical result shows that the new combined materal block could transfer the clamping force to coiled tubing more effectively,and the contact stress significantly increased and distributed more evenly,which improved the reliability of clamping effectively. |
