Lecture 19 - Failure mode and effects analysis FMEA. The following will be discussed in this chapter: Phases of engineering design, engineering design process, failure mode and effects analysis, FMEA in design and maintenance,. | Design web Design web Objectives for today ME 1110 – Engineering Practice 1 Engineering Drawing and Design - Lecture 19 Lear FMEA – one of the methods for assessing potential failure and their effects Failure Mode and Effects Analysis FMEA Prof Ahmed Kovacevic School of Engineering and Mathematical Sciences Room CG25, Phone: 8780, E-Mail: 1 Ahmed Kovacevic, City University London 2 Ahmed Kovacevic, City University London Design web Design web Phases of Engineering Design 3 Ahmed Kovacevic, City University London 4 Ahmed Kovacevic, City University London Design web Design web Engineering Design Process Failure Mode and Effects Analysis A failure mode is any event, which causes a functional failure of a machine or a system! Phase 1 (Concorde Window) Failure effects describe what happens when a failure mode occurs Phase 2 (Satellite hinge) Phase 3 (Car axle/Helicopter) Phase 4 (Paper structure) Phase 5 5 The best way to address all failure modes and to estimate their effects is to list all functions and to analyse how each of these can fail and what causes will it make.

MOVIES 2. 3. 4. 5. 6. 7. 9 Ahmed Kovacevic, City University London FUNCTIONS - What are the functions and associated desired standards of performance of the asset in its present operating context? FUNCTIONAL FAILURES - In what ways can it fail to fulfil its functions? FAILURE MODES - What causes each functional failure? FAILURE EFFECTS - What happens when each .
