Title:
【発明の名称】回転体の振動の非接触測定方法
Document Type and Number:
Japanese Patent JP2003531367
Kind Code:
A
Abstract:
Stationary sensors are used to measure periodically the vibratory motions of portions of a body spinning in front of them, such as blades, and to try to determine their natural frequencies by spectral analyses. The sensors are collected together in several networks of different numbers and the determination includes a comparison of the spectra of the different networks via different operations of selection and rejection of lines. The process appreciably pushes back the limit of unambiguous frequency detection.
