Abstract:
System and method for active detection of asymmetry in a rotating structure, the method comprises: imparting harmonic mechanical excitation on the rotating structure that is asynchronous to the speed of rotation of the structure; obtaining a response from the excited rotating body; and analyzing the response to determine a presence of modulation of the imparted harmonic mechanical excitation, that causes vibration at a frequency that is a combination of both the harmonic mechanical excitation and the modulation speed of rotation.
