摘要

A synchronous cycle-ratio analysis is presented in the paper. The new method considers 2π as a basic cycle, which embodies the characteristics of 2π cycle in rotating machinery. The new method overcame the shortcomings of order analysis. An experiment verified that the new method is very effective, which can excellently filter random noise by statistically synchronous averaging of samples, and the cycle-ratio leakage can be eliminated perfectly. The peak values of synchronous cycle-ratio spectrum is not only clear without noise and leakage, but can be used to identify the related physical parameters, which will be very useful for trouble shooting of rotating machinery.
