An experimental system was designed to measure dynamic responses of non-rotating blade, in which the similar stress and strain fields can be recreated similar to a blade which is fixed to its disk by means of dovetail. During the experiments, the beam was subject to different tensile loads and excitation forces. The dynamic response was measured while the beam was vibrating as various modes. The effects of tensile load, excitation load and contact condition at bladed disk joints on the resonance frequency and resonance response level were analyzed from the test results. These results could be used to explain the measured dynamical response in view of the behavior at the interface.
