摘要： PROBLEM TO BE SOLVED: To provide a turbine generator which can prevent the crack and the breakage of an insulating layer by suppressing vibration at the winding end of a stator, and a vibration suppressing method of the winding end of the stator of the turbine generator.
SOLUTION: There are provided means (12 to 15, 17 and 18) for changing the vibration responsiveness of the winding end 3 of the stator overhanging from a stator core 1 according to an operation status. Since natural vibration can be changed by controlling the vibration responsiveness of the winding end 3 of the stator by arranging the means (12 to 15, 17 and 18) according to the operation status as above, approximation to an operation frequency of the turbine generator can be avoided, and as a result, the crack and the breakage of the insulating layer (10) can be prevented by suppressing the vibration of the winding end 3 of the stator.

摘要： PROBLEM TO BE SOLVED: To solve the following problem: when no measure against vibration is taken in a cooling pipe connecting a winding coil and a liquid inlet header and a liquid outlet header; and when the cooling pipe resonates and vibrates with large amplitude, high stress is produced in not only the cooling pipe but also the headers and winding coil to which the cooling pipe is attached and the lives of these points are shortened.
SOLUTION: In a power generator stator, a cooling pipe for guiding cooling liquid to a winding coil includes a flexible line or a flexible line 10b having a curvature and its end portions have higher rigidity than the flexible line. The natural frequency of the cooling pipe is set to a value higher than an electromagnetic exciting frequency by increasing the rigidity of the end portions of the cooling pipe. This makes it possible to prevent the cooling pipe from resonating and high stress from being produced in the cooling pipe or its attachment portions.

摘要： PROBLEM TO BE SOLVED: To improve the reliability on the superconductive magnet of a linear motor train by varying the natural frequency of at least one inner vessel out of a plurality of inner vessels from those of other inner vessels, within one outer vessel. SOLUTION: For a superconductive magnet, 8-a, 8-b, 8-c, and 8-d different in rigidity are used as the load supports 8 to support and fix four pieces of inner vessels 2-a, 2-b, 2-c, and 2-d housing superconductive coils. Then, the natural frequencies of the inner vessels 2 come to severally different values, because the spring constants of the load supports 8 are all put to different values by putting the diameters of the cylinder parts 8C-a, 8C-b, 8C-d of the load supports 8 to severally support and fix the four pieces of inner vessels 2a-2d in severally different sizes. Further, the dispersion of the natural frequency is determined to be roughly 5%. As a result, it becomes to prevent the four pieces of inner vessels from resonating at the same time, and the reliability on the supperconductive magnet for a linear motor train can be improved by reducing heat generation.
