Practical Case Studies On Vibration Analysis Pdf Jun 2026

If you are compiling these case studies into a training reference or a predictive maintenance manual, let me know. I can expand on more complex failure modes like , fluid-film sleeve bearing instability (oil whirl/whip) , or provide the complete mathematical formulas for calculating rolling element defect frequencies (BPFO, BPFI, BSF, FTF) .

A gearbox in a power generation plant was experiencing high vibration levels, leading to concerns about its reliability. A vibration analysis was conducted using a vibration analyzer. The results showed a high level of vibration at 2 times the gear mesh frequency (2x GMF). This indicated a potential problem with misalignment of the gearbox. Upon inspection, it was found that the gearbox was indeed misaligned, causing the gears to mesh improperly. The gearbox was realigned, and the vibration levels returned to normal.

Remember the three golden lessons from our case studies: If you are compiling these case studies into

Because the vibration analysis PDF case study included historical data, the team knew the sideband amplitude had doubled in 3 months. The gearbox was pulled during a scheduled shutdown. The planet bearing was found with flattened rollers, and the sun gear had a hairline crack visible only via dye penetrant. A vibration analysis was conducted using a vibration
