For the purpose of the reliability improvement, a friction damper is sometimes adopted in the vane of the gas turbine compressor. In order to verify the damping characteristic of the damper vane, the non-contact magnetic exciter was made and the excitation test of the damper vane was carried out. On the other hand, the analysis code was developed for predicting the damping characteristic of the damper vane. The frequency and damping of the damper vane measured by the excitation test was compared with the calculated results. The results of the test and the analysis showed that the damper vane has a excellent damping characteristic.
