What is the primary purpose of Failure Mode and Effects Analysis (FMEA)?
Answer: To systematically identify potential failure modes and their consequences to prioritize mitigation
FMEA evaluates potential failure modes, their causes, effects, and assigns risk priority numbers to guide reliability improvement.
Which condition monitoring technique uses high-frequency sound waves to detect leaks and bearing defects?
Answer: Ultrasonic testing
Ultrasonic testing detects high-frequency sound waves from turbulence, electrical discharge, and friction that are inaudible to humans.
What is the Weibull distribution commonly used for in reliability engineering?
Answer: Modeling equipment failure patterns and estimating reliability parameters
The Weibull distribution models failure data and characterizes failure patterns as early life, random, or wear-out failures.
What is the purpose of dynamic balancing for rotating equipment?
Answer: To correct mass distribution imbalances that cause vibration and premature wear
Dynamic balancing corrects uneven mass distribution, reducing vibration forces that cause accelerated bearing wear and fatigue failures.
Which reliability metric represents the probability that equipment will perform its function for a specified period?
Answer: Reliability
Reliability is the probability that equipment will perform its intended function without failure for a specified period under stated conditions.
What is the purpose of a failure reporting, analysis, and corrective action system (FRACAS)?
Answer: To systematically capture failure data, analyze root causes, and implement corrective actions
FRACAS provides a closed-loop system for recording failures, investigating causes, and implementing corrective actions.
