Robust IFE Based Order Analysis of Rotating Machinery in Virtual Instrument
Character analysis plays an important role in fault-find and diagnosis of rotating machinery. Order analysis is one of the major methods in character analysis for the analysis of non-stationary vibration signals in run-up or coast down of rotating machinery. An order analysis method, which employs instantaneous frequency estimation based on time-frequency analysis, is introduced. In contrast with traditional order analysis methods, this method avoids the use of tachometer and other special hardware; hence it makes the application of order analysis simplified. The order analysis introduced in the paper with the character that only software is depended for order tracking makes it specially satisfy the requirement of Virtual Instruments. Corresponding order analysis items, such as order spectrum, order spectrum matrix and tracking order spectrum etc., which are applied in Virtual Instruments, are also introduced. A test example is provided to demonstrate the validity of the method presented.
