The damping ratio provides a mathematical means of expressing the level of damping in a system relative to critical damping.
12.
This damping ratio is just a ratio of the actual damping over the amount of damping required to reach critical damping.
13.
Where the attenuation \ alpha, and Q factor Q ( i . e ., damping ratio \ zeta ) are given by
14.
I'd probably do a PD or phase lead if I wanted to increase the damping ratio or speed the system up.
15.
The exponential term defines how quickly the system damps down the larger the damping ratio, the quicker it damps to zero.
16.
The natural frequency and damping ratio are not only important in free vibration, but also characterize how a system behaves under forced vibration.
17.
The plots to the side present how 0.1 and 0.3 damping ratios effect how the system rings down over time.
18.
In engineering, the "'damping ratio "'is a dimensionless measure describing how oscillations in a system decay after a disturbance.
19.
"' Logarithmic decrement "', \ delta, is used to find the damping ratio of an underdamped system in the time domain.
20.
CNF s have also been shown to provide good electrical conductivity ( important for lightning strikes ), high damping ratio, and good impact-friction resistance.
