Development of an Experimental Facility for Analysis of Rotordynamic Phenomena

摘要

An experimental facility was developed to investigate the rotordynamic phenomenaof rotating machinery during subcritical, resonant and supercritical operation. The behavior of the rotor was characterized throughout the operating range. The facility consists of a Bentley Nevada Corporation Rotor Kit integrated with a computerized data acquisition and control process. A LabVIEW Virtual Instrument was designed to collect, analyze and display rotor position and rotor displacement information. Experiments conducted included construction of Cascade plots, analytic prediction of the first lateral mode and demonstration of synchronous whirl due to a mass imbalance; during which, backward whirl was experienced.
