logarithmic decrement

基本解釋

The results show that the logarithmic decrement of the system is greatly increased when it is equipped with the damper.
結(jié)果表明：裝配阻尼器后的轉(zhuǎn)子系統(tǒng)其對數(shù)衰減率有了很大提高。

Finally, the natural frequencies and damping ratios of the structure can be found from these signatures by logarithmic decrement method.
最后，用對數(shù)減縮法，由這些曲線求出結(jié)構(gòu)物的固有頻率和阻尼比。
The important action of eigenvector in estimating stability margin is investigated, and the limitation of both system damping and logarithmic decrement criteria is pointed out.
探討了特征向量在評估穩(wěn)定性裕度的重要作用，指出了傳統(tǒng)的對數(shù)衰減率與系統(tǒng)阻尼判據(jù)在評估軸承穩(wěn)定性裕度時的局限性。
