These techniques provide a machine analyst with a tool kit to better understand signature anomalies in rotary machines. With their application, the analyst can make confident judgments as to whether or not a newly found and unusual signature pattern is caused by a defect. Once the analyst decides or whether the pattern is defect related, he can evaluate its implications with fresh insight. Over the years, Space Shuttle condition monitoring has both stimulated the creation of these tools and benefited by their application to resolving SSME pump problems. These techniques have been incorporated into a software product called PC-SIGNAL. The software operates on a Pentium II-based computer under the Windows operating system. PC-SIGNAL includes many analysis capabilities for both conventional and advanced methods to analyze vibration dynamic strain, dynamic pressure and sound. The newly available software provides a user-friendly version of these tools for use on a well-equipped windows-based personal computer Now, engineers in all industries who are confronted with unexpected problems in rotary equipment operation can apply these highly effective diagnostic methods.
