| 1. | A nominal level of damping is assumed ( 5 % of critical damping ).
|
| 2. | For the case of critical damping,
|
| 3. | If the damping is increased past critical damping, the system is " overdamped ".
|
| 4. | The value that the damping coefficient must reach for critical damping in the mass spring damper model is:
|
| 5. | The damping ratio provides a mathematical means of expressing the level of damping in a system relative to critical damping.
|
| 6. | This damping ratio is just a ratio of the actual damping over the amount of damping required to reach critical damping.
|
| 7. | Ideally, the natural frequency should be high and the damping factor should be near 0.707 ( critical damping ).
|
| 8. | The value of damping that causes the oscillatory motion to settle quickest is called the critical damping C _ c \,:
|
| 9. | The special case of 1 } } is called critical damping and represents the case of a circuit that is just on the border of oscillation.
|
| 10. | If damping is increased just to the point where the system no longer oscillates, the system has reached the point of " critical damping ".
