Vibration monitoring data interpretation 2

[Alan CA]

Hi everyone,

Guidelines, related to construction vibration monitoring, present maximum allowed values for vibration parameters. However, these guidelines do not show how to look at the vi ration monitoring data and how to interpret them.
Anybody has got samples of vibration monitoring data, illustrating prohibited values or guidelines on how to interpret the data?

you need the monitoring company to give you peak particle velocity (PPV), not much else to it

At PPV vs Frequency plot from 0 to operating speed, or other limits of interest.
How you interpret the data depends on type of equipment and/or if its solely for evaluating mechanical response or also includes human perception.
These will get you started.

Einstein gave the same test to students every year. When asked why he would do something like that, "Because the answers had changed."

Caltrans has some good data on vibration, including interpretation

Thank you for your answers. What I need is a sample of the results shkwing vibration that is acceptable or excessive. I just want to take a look at the monitoring results

Acceptable and excessive depend on what is vibrating and if anybody is feeling it.
High amplitude slow frequency doesn't do anything to a boat on an ocean wave, but if someone is in the boat, they might be seasick. High frequency low amplitude might smash your wine glass, but the sliding glass door remains undamaged.
