A motor is mounted on a platform that is observed to vibrate excessively at an operating speed of 6000 rpm, producing a 250 N force. Design a vibration absorber (undamped) to add to the platform such that the displacement of the motor becomes zeo. Note that in this case, the absorber mass will only be allowed to move 2 mm because of geometric and size constraints.

Concept explainers

Free Damped Vibrations

Free vibration is a type of vibration in which the external force is removed after giving the initial displacement to a body/system. In other words, in this type of vibration, force is applied at the initial displacement of the system, and after the initial displacement, force is removed, and the system vibrates at the natural frequency.

Question

A motor is mounted on a platform that is observed to vibrate excessively at an operating
speed of 6000 rpm, producing a 250 N force. Design a vibration absorber (undamped) to
add to the platform such that the displacement of the motor becomes zeo. Note that in this
case, the absorber mass will only be allowed to move 2 mm because of geometric and size
constraints.
