[Abstract]:The principle and harm of fatigue failure of high pressure tubing are expounded. A mechanical model for evaluating welding quality of high pressure tubing is established. The allowable displacement input is calculated by finite element analysis technique and combined with strain measurement technology. The fatigue characteristics of high pressure tubing welding are verified by using electric vibration table. The results show that the welding quality evaluation method of high pressure tubing is feasible. The combination of finite element analysis and strain measurement technology ensures the safety and accuracy of the test results. In addition, the use of electric vibration table for fatigue durability test, easy to operate, relatively low cost. Universal.
