Why vibration isolation frequency matters — Vibrasure

Jun 08, 2021Remember, though, that a vibration isolator only isolates at frequencies above 1.4x the spring resonance. And all isolators of this sort provide more attenuation at higher frequencies, and less attenuation at lower frequencies. That means that neoprene is great for acoustical problems: a 12Hz isolator might provide attenuation for frequencies

Oct 27, 2021The vibration isolation at the midspan position is 16 dB, and the vibration isolation at the junction is between 10 and 12.4 dB. The isolation effect of each frequency band is shown in Figure 15 . As can be seen, the vibration isolation effect of the midspan and the wall-floor junction mainly occurs in the frequency band of 40∼80 Hz.

Vibration Isolation

Good vibration isolation and damping are essential for STM. Since the STM scan head is fairly rigid, low frequency oscillations will only cause the entire STM head to oscillate, without affecting the tip-sample distance, but higher frequencies will cause problems. I live near a highway and airport, so I went for a fairly elaborate setup. The STM head

Vibration isolation (defined as T1) occurs when the excitation frequency is1.4 f n. For minimum transmissibility (maximum isolation), the excitation frequency should be as high above the natural frequency as possible.

Vibration Isolation Theory: Unfortunately (but fortunately for noise control consultants), this is not always possible. A typical problem is a rotating machine (such as a pump, AC compressor, blower, engine etc) mounted on a roof, or on a floor above the ground floor. The problem is usually most apparent in the immediate vicinity of the vibration source.
