tärinäanalyysi

Tärinäanalyysi, or vibration analysis, is a diagnostic technique used to detect and diagnose problems in rotating machinery. It involves measuring the vibrations produced by a machine and analyzing their characteristics to identify potential faults. These faults can include issues with bearings, gears, rotors, and imbalance.

The principle behind tärinäanalyysi is that machine faults generate specific vibration patterns. For instance, a worn bearing might produce a high-frequency vibration, while an imbalance in a rotor will cause a vibration at the rotational speed of the machine. By monitoring these vibrations over time, engineers can identify changes that indicate a developing problem.

Commonly used tools for tärinäanalyysi include accelerometers, which convert vibration into electrical signals. These signals are then processed by specialized software that can perform various analyses, such as time-domain analysis, frequency-domain analysis (using techniques like Fourier Transform), and envelope analysis.

The benefits of tärinäanalyysi are significant. It allows for predictive maintenance, meaning potential failures can be identified and addressed before they cause catastrophic breakdowns, leading to reduced downtime, lower repair costs, and improved operational safety. It is widely applied in industries such as manufacturing, power generation, and transportation.
