frequency of vibration of the normal modeとは 意味・読み方・使い方

In the space where proper vibration is difficult to attenuate, and also sound waves with a low frequency are propagated, noise with a comparatively low frequency strongly depends on a normal mode of vibration.例文帳に追加

固有振動が減衰しにくく、且つ低周波数の音波が伝播する空間では、比較的低い周波数の騒音は固有振動姿態の態様に強く依存する。 - 特許庁

Moreover, in the method, the frequency response function is compared on the basis of a difference from a reference frequency value of a specific vibration in a normal mode, thereby judging the life of the transfer roll 3 in the furnace.例文帳に追加

さらに、周波数応答関数の比較の際、特定の固有振動についてその振動数の基準値との差に基づき炉内搬送ロール３の寿命を判定する炉内搬送ロールの寿命判定方法 - 特許庁

The inventors think that on the contrary to the above, when sound pressure is reduced by a resonance unit taking a loop part of sound pressure of the normal mode of vibration as a controlled object, the sound with that frequency can be effectively attenuated in the whole space.例文帳に追加

これに対し、固有振動姿態の音圧の腹の場所を制御対象として共鳴体により音圧を低減させれば、空間全体でその周波数の音を効果的に減衰させることができると発明者らは考えた。 - 特許庁

This failure diagnostic system has: a detecting device for detecting at least one of the vibration and the noise generated from the electric blower; and a control means for detecting the failure of the electric blower and determining the failure mode by comparing at least one frequency component of the vibration and the noise detected by a detecting means, with a frequency component characteristic of a normal electric blower.例文帳に追加

電動送風機から発生する振動及び騒音の少なくとも１つを検出する検出装置と、検出手段で検出された振動及び騒音の少なくとも１つの周波数成分を、正常な電動送風機に特有な周波数成分と比較することで電動送風機の故障検知及び故障モード判定を実行する制御手段と、を有することを特徴とする。 - 特許庁

Resonators 32a and 32b resonating at a specific resonance frequency generated in the inner space due to driving of the speakers 30a and 30b are provided so that a control point is located at a sound pressure loop in a vibration normal mode of the resonance frequency in the inner space, and sound pressure in the sound pressure loop is reduced by resonance of the resonators.例文帳に追加

スピーカ３０ａ、３０ｂの駆動により内部空間に生じる特定の共鳴周波数で共鳴する共鳴器３２ａ、３２ｂが、内部空間における当該共鳴周波数の固有振動姿態の音圧の腹に制御点が位置するように設けられ、共鳴器の共鳴により当該音圧の腹における音圧を低減させる。 - 特許庁
