Well explained Adash.....👍 It helps me more As I'm Fresher this video gave more knowledge. Because tomorrow I have an interview in CMS So that I just prepare some basics... And it helps me lot........ Thank you and Team........
Thank you for the really nice video with wonderful animations. easy to understand. my question is on physical implication of velocity. you measure acceleration on the machine and choose to look at velocity value. what/how does velocity help to understand vibration better than acceleration or displacement?
Very simply speaking. Velocity is mostly used for lower frequencies for the whole machine body vibrations related to the speed of the machine where you are looking for faults such as unbalance, misalignment, mechanical looseness etc. Velocity simply works the best for that. On the other hand higher vibrations of bearings are more "visible" using acceleration measurement. Displacement mostly measured by proximity probes on turbines for more sophisticated measuremets of Orbits, Centerline etc.
There is no human being who can answer to this general question. Ok, we can answer like this: We are measuring vibrations in velocity unit and measured object is vibrating 4 mm/s. But I guess this answer will not help you. Please write us on info@adash.com with more details about your vibration measurement and we will try to guide you.
How could I obtain the relevant acceleration by taking into account the Fourier transform? Because if you use the Simple Harmonic Motion, acceleration will always increase as frequency increases. In reality, structures are affected by certain frequency. So, how can I consider both the peak acceleration and the frequency in which my structure will have resonance effects?
We would like you to elaborate your topic more please as it is not totally clear to us. Please write on our technical / sales support for further discussion: revaj@adash.cz
Very good explanation, I have a question, a lot of data is required to do this vibration analysis? Why if monitoring is done all day then we will have the storage problem, right?
hi, if i have acceleration, displacement, amplitude, velocity, frequency, how can i use that data to generate future values of my sine wave? I want to see how the sine wave will look with vibration.

Cummins Allison 852 Feehanville Drive Mount Prospect,IL 60056 fired me after 16 years loyal service because I would not stylus whip pm tickets for their own pm paying customers like Dover Downs in Delaware. The DOJ here blew off my report and that hit real hard to my integrity. Fired and Blackballed...sad :(
