sivuvärinät
Sivuvärinät, a Finnish term, translates to "side vibrations" or "parasitic vibrations" in English. It refers to unwanted oscillations or vibrations that occur in a mechanical system alongside the primary intended motion or vibration. These side vibrations are often a consequence of the system's design, manufacturing tolerances, material properties, or operating conditions. They can arise from various sources such as imbalances in rotating parts, structural resonances, fluid flow instabilities, or even external disturbances.
The presence of sivuvärinät can have several detrimental effects. They can lead to increased noise levels,
