Abstract
A rotary machine includes: a pair of radial bearings for rotatably supporting a rotating shaft around a center axis; impellers fixed to the rotating shaft at positions separated from the radial bearings in a center axis direction; and additional masses fixed to the rotating shaft at positions separated from both the radial bearings and the impellers in the center axis direction, and applying a load to an entire circumference of the rotating shaft so as to move positions of amplitude increase regions where an amplitude in a radial direction of the rotating shaft starts to increase.
