ENGR 100 Lecture Notes - Lecture 16: Failure Mode And Effects Analysis, Hair Dryer, Power Cord
Document Summary
Failure mode and effects analysis and its variations (fmea) components. Bottom-up process estimates reliability of complex systems from reliability of. Analysis done by completing a table and following logical rules. Full details of the component, equipment, process, or complex, facility must be available. (i. e. drawings, design sketch, standards, product specifications, test results, etc. ) Identify each component by part name and number. List all ways (modes) in which each component can fail. Determine effects of failure on other components and on unit. Describe how to detect each failure mode: failure modes, effects and criticality analysis (fmeaca) Adds an assessment of criticality to the fmea method. Indicate action needed to eliminate hazards and identify person responsible for that actions. Assess criticality of each failure mode and its probability of occurrence. All events that cause top event are determined. Contributory events are then analyzed to determine events that cause them. Keep going down chain of events root causes.
