Measurment of frequency response by vibro-dynamic exciter

The vibro-dynamic exciter consists of an eccentric mounted on the shaft of an electric motor.
Once the exciter is rigidly attached to the frame, it is put into rotation and accelerated up to 6000rpm.
In this way, the structure is excited at various frequencies by means of the centrifugal force generated by the rotation of the eccentric. The vibro-dynamic exciter is very useful when it's necessary to measure the frequency response of heavy structures

Example of application of the exciter to a portal milling machine.
