logarithmic decrement

基本解释

The results show that the logarithmic decrement of the system is greatly increased when it is equipped with the damper.
结果表明：装配阻尼器后的转子系统其对数衰减率有了很大提高。

Finally, the natural frequencies and damping ratios of the structure can be found from these signatures by logarithmic decrement method.
最后，用对数减缩法，由这些曲线求出结构物的固有频率和阻尼比。
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.
探讨了特征向量在评估稳定性裕度的重要作用，指出了传统的对数衰减率与系统阻尼判据在评估轴承稳定性裕度时的局限性。
