Title:
DEVICE FOR MEASURING DYNAMIC CHARACTERISTICS OF CENTRIFUGAL-TYPE ROTARY MACHINE, AND CENTRIFUGAL-TYPE ROTARY MACHINE
Document Type and Number:
WIPO Patent Application WO/2014/077275
Kind Code:
A1
Abstract:
This device for measuring dynamic characteristics is provided with: magnetic force generators (1a, 1b, 2a, 2b) that are positioned at the back sides of impellers (4, 5), and vibrate the impellers (4, 5) via magnetic forces; a vibration controller (12) that drives the magnetic force generators; and vibration sensors (13, 14) that detect the vibrations of a rotary shaft (3). The device for measuring dynamic characteristics is further provided with an arithmetic device (16) that calculates the dynamic characteristics of a rotor (6) by performing frequency analysis and modal analysis on the basis of a vibration signal from the vibration controller (12), and vibration signals from the vibration sensors (13, 14).
