Analysis of damp trial result of Ti17 simulation blade in air

Through simulation blade's damp trial in air,various order vibration model attenuation coefficients have been achieved by the method of free vibration attenuation,then various order vibration model damp ratios were obtained,and the ratio damp coefficients were deduced.These could offer reference for analysis of the relationship between the blade's damp and vibration model in nature and deciding the damp coefficient when calculating the response.
