case study of vibration analysis pdf

This case study concerns a screw compressor operating in offshore. process environment with unpredictable gas composition. The compressor was tripped on high vibration during startup after seals replacement. Analysis of the acquired transient vibration data indicated rub as secondary cause of the high vibration, and improper timing gears ...

Vibration monitoring: In vibration monitoring, the real-time data is collected which is graph of time verses amplitude. The condition monitoring and detection analysis of rotatory type of machines by means of vibration were studied [6]. Every part of the rotating machinery has some frequency, and for every frequency, there is amplitude.

The different case studies that I carried out at different industries contains the Balancing problems, misalignment issues and Resonance, which we removed by Balancing, alignment across coupling and dynamic vibration absorbers. In one of the case study we made the decision for location of CMM machine through vibration analysis.

1) Vibration problems involving resonance require modal analysis to identify natural frequencies and mode shapes. Only modal data is scaled properly to be used for the evaluation of potential modifications to solve the resonance problem. 2) Operating deflection shape is a 3-dimensional analysis procedure whereas Vibration Video

The condition monitoring and detection analysis of rotatory type of machines by means of vibration were studied [6]. Every part of the rotating machinery has some frequency, and for every frequency, there is amplitude. This amplitude changes whenever there is fault in the respective parts of the machinery.
