tärinäanalyysiä

Tärinäanalyysiä, often translated as vibration analysis, is a diagnostic technique used to detect and diagnose faults in rotating machinery. It involves measuring the vibrations produced by a machine while it is in operation. These vibrations are then analyzed to identify patterns that indicate specific types of mechanical problems. The underlying principle is that as machinery components wear or become damaged, they generate unique vibration signatures. By capturing and interpreting these signatures, technicians can pinpoint issues such as imbalance, misalignment, bearing defects, gear wear, and looseness before they lead to catastrophic failure.

The process typically begins with the installation of accelerometers or velocity transducers onto the machine's casing or bearing housings. These sensors convert mechanical vibrations into electrical signals. The signals are then processed by specialized equipment, such as vibration analyzers or data collectors, which can perform various types of analysis. Common analytical methods include time-domain analysis, which examines the vibration signal over time, and frequency-domain analysis, which breaks down the signal into its constituent frequencies. Specific frequencies are associated with different fault conditions, allowing for targeted diagnosis.

Regular vibration analysis is a cornerstone of predictive maintenance programs. It enables maintenance teams to schedule repairs proactively, minimizing unplanned downtime, reducing repair costs, and extending the lifespan of critical equipment. Early detection of faults through tärinäanalyysiä is crucial for maintaining operational efficiency and safety in industries ranging from manufacturing and power generation to transportation and aerospace.
