The Many Uses of a Vibration Dampening Pad -

Engineers are, perhaps, the ones who have most need for a vibration dampening pad once in a while. Such a pad can help them keep their engines and inventions working more smoothly and efficiently. Vibration, you see, can cause excess noise in a machine, which is annoying. It can also, though, cause parts to rub against one another, making a machine more likely to break down over time and causing .

Vibration - Wikipedia

More damping actually reduces the effects of vibration isolation when r ≫ 1 because the damping force (F = cv) is also transmitted to the base. whatever the damping is, the vibration is 90 degrees out of phase with the forcing frequency when the frequency ratio r = 1, which is very helpful when it comes to determining the natural frequency of ...

Vibration Damping — Copter documentation - ArduPilot

Vibrations are short coupled, so all that leaving excess corner clearance does is to require higher initial O-ring tension which reduces vibration damping responsiveness and allows the board to physically tilt more (which is undesirable as it throws the sensor to airframe relationship off).
