Performance measuring system and method for analyzing performance characteristics of rotating shafts

摘要

A performance measuring system for a rotating shaft comprises a first annular support assembly to be coupled adjacent to a first end of a rotating shaft inwardly of associated shaft bearings. A second annular support assembly is to be coupled adjacent to a second end of a rotating shaft inwardly of associated shaft bearings. A third annular support assembly is to be coupled to the rotating shaft between the first and second support assemblies. A laser source is mounted on the first annular support assembly. A laser detector is mounted on the second annular support assembly. First and second magnetic sensors for detecting the Earth's magnetic field are mounted respectively on the first and second annular support assemblies. An accelerometer is mounted on the third annular support assembly for generating a fourth detection signal.
