Critical Damping

临界阻尼

Critical damping provides the quickest approach to zero amplitude for a damped oscillator. With less damping (underdamping) it reaches the zero position more quickly, but oscillates around it. With more damping (overdamping), the approach to zero is slower. Critical damping occurs when the damping coefficient is equal to the undamped resonant frequency of the oscillator.

临界阻尼使阻尼振子最快地达到零振幅。在阻尼较小（欠阻尼）的情况下，它更快速地达到零位置，但会围绕它振荡。在阻尼较大（过阻尼）的情况下，达到零振幅的过程更慢。临界阻尼发生在阻尼系数等于振子无阻尼共振频率时。

Overdamped Oscillator

过阻尼振子

Overdamping of a damped oscillator will cause it to approach zero amplitude more slowly than for the case of critical damping. The damping coefficient is greater than the undamped resonant frequency .

过阻尼的阻尼振子会比临界阻尼情况更缓慢地使振幅趋于零。阻尼系数大于无阻尼共振频率。
