Vibration in helicopter can be caused by many different reasons. I am interested to know what is the range of amplitude of vibration?
I am interested to know how amplitude varies with frequency of vibration? I am looking for an answer in terms of distance from a reference or equilibrium or stopping condition. For example does the maximum distance (amplitude) from the reference is 2 cm or less or more when helicopter moves?
I understand that it would depend on the helicopter type. So any reference to such analysis would be appreciated.
This is similar/extention to the question What is the range of frequencies of vibration in a helicopter due to the main rotor alone? where it asked about frequency of rotor.
