Failure analysis is a systematic method used to identify and evaluate potential faults, defects, and failure forms in a system, equipment, or process. It can help organizations prevent accidents and malfunctions, reduce risks and losses in production and service processes. The following are the basic procedures and main steps of failure analysis:

Determine Failure Mode

Failure modes refer to various faults, defects, and failure forms that may occur in a system, equipment, or process. When determining the failure mode, the following aspects can be taken into consideration:

Identify various failure modes through on-site observation, equipment testing, fault simulation, and other means;

Analyze the product and analyze various possible faults and their causes that may occur during production and use.

Determine the cause of failure

The cause of failure refers to the fundamental cause that causes the failure mode to occur. When determining the cause of failure, it is necessary to analyze the causes and effects of failure modes, in order to identify various potential causes of failure. The following measures can be taken during this process:

Analyze using methods such as flowchart and causal diagram;

Analyze various factors that lead to failure through data analysis techniques such as fault analysis tree and fault mode effect analysis (FMEA).

Evaluate the impact of faults

When evaluating the impact of a fault, it is necessary to consider the impact of the fault on production and service processes, equipment and systems, work environment, and safety. Assessing the impact of a fault can determine its urgency and severity, and develop targeted repair measures.

Develop repair measures

Based on the analysis of failure modes, causes, and effects, develop repair measures including improving design, optimizing equipment maintenance, and improving process flow. Each measure should be associated with a specific failure mode, cause, and impact of the failure.

Implementation and monitoring

Implement the repair measures into practical operations, and evaluate and monitor their effectiveness. Specifically, the following work should be carried out:

Select the time and location for implementing measures, and arrange a dedicated person to be responsible for implementing the measures;

Monitor the implementation of measures and promptly identify and handle abnormal situations.

Failure analysis should be a cyclic process that continues to analyze faults, improve processes, and equipment. An effective failure analysis program requires a systematic and structured approach that takes into account all aspects, including material, equipment, process, and personnel factors. Only in this way can failure analysis ultimately achieve its expected results and provide organizations with safe, reliable, and efficient production and services.
