ROTARY MACHINE VIBRATION MEASURING DEVICE, ROTARY MACHINE VIBRATION MEASURING METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a highly precise rotary machine vibration measuring device, rotary machine vibration measuring method and program.;SOLUTION: A vibration measuring device for rotary machines is equipped with a vibration calculating unit 11 that calculates the vibration of a casing 120 on the basis of the vibration model of the casing 120, a first rotating body vibration calculating unit 14 that calculates the vibration of the turbine blades 111 on the basis of the time difference between the passage time of detection of turbine blades 111 by a non-contact sensor 3 and the passage time of the turbine blades 111 in a reference state, and a second rotating body vibration calculating unit 15 that removes from the vibration waveform of the turbine blades 111 calculated by the first rotating body vibration calculating unit 14 displacement due to vibration of the casing 120 in a first prescribed position calculated by the vibration calculating unit 11 and calculates the vibration of the turbine blades 111.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
