Methods and measuring systems for calibration of non-contact vibrodiagnostics systems

Popis výsledku v původním jazyce

The paper deals with methods and measuring systems for calibration of non-contact vibrodiagnostic systems sed for operational monitoring of blades in steam and gas turbines. The principal of the blade tip-timing vibrodiagnostic system is explained as well as the function of the non-contact magnetoresistive sensor. Appliances for the static calibration of the system are described based on a position traverser with a micrometer shift. The main emphasis of the paper is given to the dynamic calibration. A 4-chip HE sensor developed specially for this purpose is shown. The deflections measured by the noncontact vibrodiagnostic system at the blade tips are calibrated by strain gauges for the determination of the stress at the blade roots. The error of the calibration is estimated on the bases of derived equations.
