Title:
ROTARY MACHINE AND VIBRATION CONTROL METHOD THEREOF
Document Type and Number:
Japanese Patent JP2016160949
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To exhibit a large vibration control effect, even in a case where the rotational frequency of a rotary machine varies.SOLUTION: A rotary machine includes: a rotary member 50 supported in a rotatable manner around a rotating shaft; a fixation support member 10 formed into a substantially cylindrical shape coaxially with the rotating shaft, and surrounding the radial outside of the rotary machine 50; a first hood damper 30a arranged at a position to be an antinode in a first circular-ring vibration mode of the fixation support member 10, and configured to generate resistance force to the radial movement of the fixation support member 10; and a second hood damper 30b arranged at a position to be a node in the first circular-ring vibration mode of the fixation support member 10, and configured to generate resistance force to the radial movement of the fixation support member 10.SELECTED DRAWING: Figure 13
