摘　　要：在常规输油过程中,油品经过管件弯头部位时速度和压力会有所突变,弯头部件外侧会受到极大的作用力,容易发生冲蚀作用,甚至会造成穿孔、破裂等。利用软件Ansys Workbench 14.0对常规输油管道弯头处进行流固耦合分析,研究了不同流速、弯径比等因素对弯头冲蚀失效的影响。研究结果表明,管道弯头外侧最容易受到冲蚀作用;弯头处的变形损坏受到多因素的影响,适当降低流速、增大弯径比能够有效地缓解冲蚀所引起的破坏;采用盲通管代替弯头也可以大大缓解弯头受到的冲蚀作用。In the process of conventional oil transportation, the speed and pressure will change suddenly as the oil pass through the pipe elbow,and the elbow part will be in a great pressure, it will be prone to erosion, and even cause perforation, rupture, etc. The fluid structure interaction analysis was carried out on the elbow of conventional oil pipeline through the general calculation software Ansys Workbench14.0 , the effects of different flow velocity and bending radius ratio on the erosion failure of the elbow were analyzed. The results show that： the outside of the pipe elbow is the most vulnerable to be eroded; the deformation and damage of elbow is affected by many factors, reducing the flow rate and increasing the ratio of the bending diameter can effectively alleviate the damage caused by erosion; using blind pipe to replace the elbow can also greatly ease the impact of the elbow.
