Vibration Analysis
Vibration Analysis is a method used to check the health of industrial machines and equipment by studying how they shake or vibrate during operation. Think of it like a doctor using a stethoscope to listen to a patient's heartbeat - technicians use special tools to "listen" to machines and spot potential problems before they cause breakdowns. This helps companies save money by fixing issues early and avoiding unexpected equipment failures. Related terms include "condition monitoring" or "predictive maintenance." This skill is particularly valuable in manufacturing plants, power stations, and any facility with large rotating equipment.

Example Interview Questions
Senior Level Questions
Q: How would you implement a plant-wide vibration monitoring program from scratch?
Expected Answer: Should explain the process of equipment assessment, setting up monitoring schedules, training staff, choosing monitoring points, setting alert levels, and creating response procedures for different scenarios.
Q: How do you determine ROI for a vibration analysis program?
Expected Answer: Should discuss tracking prevented failures, maintenance cost savings, reduced downtime, extended equipment life, and comparing these against program costs including equipment, training, and labor.
Mid Level Questions
Q: What are common machine problems you can identify through vibration analysis?
Expected Answer: Should mention issues like unbalance, misalignment, loose parts, bearing problems, and be able to explain how each shows up in vibration readings in simple terms.
Q: How do you decide how often to check different types of equipment?
Expected Answer: Should explain how to set monitoring frequencies based on equipment criticality, operating conditions, and past history of problems.
Junior Level Questions
Q: What basic safety procedures should be followed when collecting vibration readings?
Expected Answer: Should discuss wearing proper PPE, being aware of moving parts, following plant safety rules, and getting proper authorization before accessing equipment.
Q: What information do you need to collect along with vibration readings?
Expected Answer: Should mention equipment operating conditions, speed, load, temperature, and any unusual observations or sounds noticed during data collection.
