vibration characteristic coefficientとは 意味・読み方・使い方

Inverse fast Fourier transform is performed based on each of the amplitude characteristic data classified by the resonance frequency and on phase characteristic data in the Fourier transform data, to thereby generate vibration waveforms classified by the resonance frequency, and a damping rate D is determined from the vibration waveform classified by the resonance frequency and a loss coefficient η is generated from the damping rate D and outputted.例文帳に追加

共振周波数別振幅特性データのそれぞれと、フーリエ変換データのうちの位相特性データとに基づいて逆高速フーリエ変換を行うことにより共振周波数別振動波形を生成し、共振周波数別振動波形から減衰率Ｄを求め、減衰率Ｄから損失係数ηを生成して出力する。 - 特許庁

The characteristic frequency of the whole of the wheel 10 is heightened cooperation of a disc 11 made of materials of a large longitudinal elastic coefficient and a rim 13 made of materials small in specific gravity and light in weight, and the road noise is reduced as resonance of the wheel 10 due to vibration of a tire 12 is prevented.例文帳に追加

縦弾性係数の大きい材料からなるディスク１１と、比重が小さく軽量な材料からなるリム１３との協働により、ホイール１０全体の固有振動数が高まり、タイヤ１２の振動に伴うホイール１０の共振が防止されてロードノイズが低減する。 - 特許庁
