PdM COE - Advanced Vibration Diagnostics

Machinery problems requiring constant maintenance can be a major drain on your maintenance budget when parts wear out prematurely and manpower has to repair the same machine over and over. MISTRAS PdM Services are experts at finding the underlying source of that nagging problem utilizing many predictive and proactive technologies.

Especially useful is the Failure Modes Effects Analysis (FMEA) method of diagnosing the source of a problem by investigating the effects of possible failure modes which exist in the machine components. This technique is also called Root Cause Engineering Analysis.

MISTRAS first looks at the possible mechanical and operational causes of failure in the bearings, or coupling, or structure, etc. Our Engineers then determine what signals or modes would be generated prior to the failure in terms of acoustics, vibration, forces, temperature, wear particles, etc. Analysis of these signals produces specific signatures which then correlate the root cause of the problem to the failure. Sometimes it's just imbalance or misalignment, but often it uncovers more difficult problem sources like soft foot and resonance conditions, or component design flaws existing in the system.

Once the real problem is discovered, MISTRAS works with your personnel to determine a final maintenance action to solve your problem once and for all, saving you downtime and maintenance costs.
