VIBRATION ANALYSIS PROGRAM.
Abstract
The objective of this program was to develop a method that could be used by technical personnel in engine field tests to reduce vibration effects encountered in jet engines. The charts that were developed are used in conjunction with the standard vibration transducer outputs during engine tests. The engine vibration problems can be determined by correlating the transducer outputs with the diagnostic charts. Three different approaches were used to get the necessary data for development of the charts: (1) Engine tests with the rotating sections unbalanced; (2) static engine tests where each section was externally excited with a simulated mass unbalance; and (3) analytical approach.
