This video explains the need for vibration mode and shape measurements in machines crystal clear !! Thanks ADASH for making such a nice video. I am a fan of your video series. :)
This is the video which explained the natural frequency determination for me
Really thanks for this video! Give a ideia pract of why mechanical engineer students (like me) should study Vibration. Amazing explanation! Greetings from Brazil!
Great video, cheers!
Buenos dias. Estimados, esta prueba se puede realizar con un sensor triaxial?.. EL equipo Va4pro tiene la posibilidad de realizar la prueba con una maquina en funcionamiento?.
Hello. Bump test is one channel measurement. Result will be the same on all 3 channels if you will measure with triaxial sensor. See this video about measuring bump test on running machine: ua-cam.com/video/no03XOy0cvU/v-deo.html
Hi, may I know is it a must for bump test results to be in g instead of mm/s?
It is not a must. I depends what physical quantity you prefer and which one is suitable for particular application.
Thanks for a very good explanation
Is that a modal hammer or a normal hammer
Hi, which parts of a motor should we perform this bump test?
Resonance frequency is the same within the whole structure. Therefore it does not really matter on which part you perform the bump test. However you should select a few points on the motor and measure FFT on them. For bump test then select point where you see the biggest response of your knocking in FFT.
@@AdashCompany When u mentioned "whole structure", does this include the DE & NDE end shields as well? Is the motor four feet the best place to conduct the bump test?
@@MrICE003 If you mean NDE fan cover which is made from weak metal sheet, then the answer is NO. It must be solid part of a machine body. You contacted also us via email so lets continue there ;-)
@@AdashCompany Sure thing 😁👍
Great video
1st & 2nd modal.
good product
Thanks dear
