How to solve the problem of fatigue fracture of aircraft forgings in accidents?
The key to solving the fatigue fracture problem of aircraft forgings in accidents lies in the following points: Fatigue detection and monitoring: For aircraft forgings, regular fatigue detection and monitoring is needed to find potential fatigue fracture problems. Commonly used testing methods include non-destructive testing technology (such as ultrasonic testing, eddy current testing, etc.) and fatigue damage monitoring system, which can find cracks, corrosion and other problems on the surface or inside the forging in time. Regular maintenance and replacement: According to the fatigue life prediction and the actual situation of the flight, develop a reasonable forging maintenance plan, and carry out the maintenance and replacement of the forging on time. This reduces the probability of fatigue breakage and ensures that the forgings operate within their safe service life. Strengthen design and manufacturing: in the design and manufacturing process of forgings, the problem of fatigue fracture should be taken into account, and corresponding measures should be taken to optimize. For example, appropriate process parameters, reasonable material selection and optimized structural design are used to improve the anti-fatigue performance of forgings. Intensive training and training: For aircraft maintenance personnel and operators, special training and training should be carried out to improve their awareness and recognition of fatigue fracture problems. This helps them find potential fatigue fracture problems in time during daily maintenance and operation, and take appropriate measures to deal with them. Strengthen information sharing and communication: Aircraft manufacturers, operators and maintenance units should strengthen information sharing and communication, and timely transfer of experience and lessons on fatigue fracture issues. This will help all parties to better understand the fatigue fracture characteristics of aircraft forgings and take preventive and solution measures. It should be noted that the fatigue fracture of aircraft forgings is a complex engineering problem, and the solution needs the comprehensive cooperation of many links. Therefore, in actual operation, it is necessary to conduct comprehensive treatment according to relevant norms and technical requirements, combined with specific circumstances, to ensure the safe operation of aircraft.
