We analyzed the bridge's characteristic vibration to see if it can withstand earthquakes.
The normal modes of this instrument change depending on the material.
Related words 共きょう 振しん 共振 (resonance) is the phenomenon where an external force matches a system's natural frequency, causing large amplitude oscillations. 固有振動 refers to the natural vibration pattern itself, not the resonant response.
固こ 有ゆう 周しゅう 波は 数すう 固有周波数 (natural frequency) is the frequency at which a system tends to oscillate in the absence of any driving force. 固有振動 is the actual vibration pattern or mode, which occurs at that frequency.
Etymology Compound of 固有 (inherent, characteristic) and 振動 (vibration, oscillation). A straightforward technical term with no unusual historical derivation.
