| Abstract: |
| As an important mechanical connection, the threaded connection has a wide range of applications covering many industries such as construction, automotive, aerospace, electric power, petrochemical, etc. The advantages of this type of connection are that it is structurally reliable, easy to connect and disassemble, and cost effective. However, in practice, environmental corrosion, vibration, external impact and other factors will have an impact on the threaded connection, resulting in its failure. This not only leads to equipment damage, but also may cause safety accidents, bringing serious economic losses and casualties to the enterprise. Therefore, carrying out in-depth study of the failure mechanism of threaded connection, and putting forward effective preventive measures accordingly to improve the safety and reliability of equipment are of great practical significance. |
