摘要： A heat exchanger tube vibration suppression device and a steam generator are provided. The heat exchanger tube vibration suppression device includes: a plurality of sleeves (101) disposed in a heat exchanger tube (66) with a predetermined gap in relation to an inner surface of the heat exchanger tube (66) so as to extend in a longitudinal direction of the heat exchanger tube; and a connecting member (102) that connects the plurality of sleeves (101) so as to be movable between a contracted position at which adjacent sleeves (101) overlap at least partially and an extended position at which the amount of overlap of the adjacent sleeves (101) is minimized. In this way, it is possible to suppress the vibration of the heat exchanger tube appropriately.

摘要： A supporting force inspection device for inspecting a supporting force of a vibration suppression member interposed between bend portions of a plurality of heat transfer tubes of a steam generator includes: an acceleration sensor for detecting a vibration state of the bend portion; a sensor holding part disposed inside the heat transfer tube and configured to hold the acceleration sensor; and a vibration force generation part configured to generate a vibration force for vibrating the heat transfer tube along a plane in which a curvature circle of the bend portion exists. The vibration force generation part is configured to cooperate with the sensor holding part and vibrate the heat transfer tube along the plane in which the curvature circle exists.

摘要： The preset application relates to a vibration damping structure for a heat-transfer tube bundle including columns arranged at an interval and each composed of a plurality of heat-transfer tubes curved in a common plane and arranged in parallel to each other. The vibration damping structure includes a first vibration damping member and a second vibration damping member disposed between the columns so as to intersect the array direction of the columns. The first vibration damping member and the second vibration damping member are disposed at different positions in an axial direction of each heat-transfer tube, and thicknesses of the first vibration damping member and the second vibration damping member in the array direction are larger than an average value of a clearance between the columns under operation.

摘要： A self-excited vibration evaluation method for evaluating self-excited vibration of a tube bundle arranged in a fluid so as to be supported by a support member includes: for each of at least one eigenmode of the tube bundle, a time history response analysis step of performing time history response analysis of simulating a change in vibration amplitude of the tube bundle, while changing a negative damping ratio corresponding to an excitation force of the fluid; a critical flow velocity calculation step of calculating a critical flow velocity of the fluid on the basis of a minimum negative damping ratio at which the change of the vibration amplitude of the tube bundle diverges in the time history response analysis; an input step of inputting an expected flow velocity of the fluid; and an evaluation step of evaluating the self-excited vibration of the tube bundle for each eigenmode by comparing the expected flow velocity of the fluid with the critical flow velocity.
