Abstract
A centrifugal rotating machine includes a rotor in which impellers are attached to the axial ends of a rotating shaft that extends in the axial direction, said impellers rotating in a rotating direction around the rotating shaft so as to draw in fluid from an intake side in the axial direction and discharge fluid from the outer side thereof in the radial direction. According to this device for measuring dynamic characteristics of said centrifugal rotating machine, a cover for covering an impeller is attached to a region of the impeller other than an intake opening on the intake side thereof, and a magnetic force generator for vibrating the impeller by magnetic force is disposed so as to face the cover.
