Reliability analysis and fault diagnosis of copper forgings of construction machinery is an important link to ensure the safety of operation and extend the service life of construction machinery. The following are some common reliability analysis and fault diagnosis methods:
1.Reliability analysis:
Failure Mode and Impact Analysis (FMEA) : By analyzing the possible failure modes of copper forgings and their impact on system performance, key issues and improvement directions are identified.
- Reliability prediction: combining the design, material, process and other factors of copper forgings, using statistical methods, mathematical models and reliability data, to predict the reliability level of copper forgings within a specified time.
- Fault diagnosis:
- Indicator monitoring and analysis: by monitoring the key indicators of copper forging, such as temperature, vibration, pressure, etc., analyze its change trend and abnormal situation, and determine whether there is a fault.
Non-destructive testing technology: such as ultrasonic testing, magnetic powder testing, etc., used to detect cracks, fatigue and other hidden faults in copper forgings. - Crack growth analysis: Crack growth analysis is carried out on the cracks that have been found, and the failure situation that may be caused by it in future use is predicted.
- Experience fault diagnosis: Diagnose the fault of copper forgings according to past experience, and find out the cause of the fault through anatomical analysis, inspection and test verification.
It should be noted that reliability analysis and fault diagnosis need to be combined with the design, use environment, material characteristics and other factors of specific construction machinery and copper forgings for comprehensive analysis to improve the accuracy and reliability of fault diagnosis. At the same time, regular maintenance and rational use of construction machinery are also important measures to ensure reliability.
