Vibration Isolation

You are asked to provide vibration isolation for a fan. The motor rotates at 3600 RPM (revolutions per minute). The fan wheel is connected to the motor by a belt, allowing it to rotate at a slower rate of 1800 RPM.

Calculate the two forcing frequencies in this system.

Which of these should be used in the selection of the isolator?

What would be the highest appropriate isolator natural frequency?

How much static deflection would be necessary to reach this natural frequency?
