| 摘要 |
The invention relates to adjacently mounted circumferentially distributed turbo machine airfoils (2a, 2b) with vibration damping systems. Each adjacent pair of airfoils (2a, 2b) comprises a fixing and receiving portion (10a, 10b), extending between the paired adjacent airfoils (2a, 2b), each with a face (12a, 12b) that are proximal or in contact with each other. Vibration is suppressed by the fixing and receiving portions (10a, 10b) each having a received magnet (20a, 20b) fixingly installed therein and a non-magnetic conducting plate (25a) therebetween. Each magnet (20a, 20b) has a pole (22a, 22b) that faces the pole (22a, 22b) of the other magnet (20a, 20b) in between which the non-magnetic conducting plate (25a) is located and in which eddy currents can be induced by the relative movement of the magnets due to vibration. |
