| Abstract: | The coupling vibration behaviors of a particular turbine rotor have been analyzed.The blades of the system were made of single-crystal nickel-based alloy and the disc was made of high temperature alloy of powder metallurgy.Therefore,the properties of these two kinds of materials were considered.The multi-coupling vibration of the rotor was studied comprehensively and the unique modal shapes were exhibited by the post-processing.Useful conclusions were derived for engineering application. |
