CHANGE OF AXES
CHANGE OF AXES
(OP)
I am working with a graphics whose axes are Double Amplitude (peak to peak) and Hz and I would like to compare this graphic with another one whose axes are Magnitude in g and Hz. Please, could someone tell me how I must translate this axes (from Double amplitude peak to peak in inch to magnitude in g). Thank you in advance. I would be very grateful if someone answer me as soon as possible.





RE: CHANGE OF AXES
1) Multiply the pk-pk values by 0.0254 and divide by 2 to obtain displacement amplitude in metres.
2) Multiply each spectral line by (2*pi*frequency)^2 to get acceleration in metres per square second.
3) Divide by 9.81 to obtain acceleration in g.

I would be very interested in more information on what is being measured and how!!

We want to construct a balance machine for cement factory fan,
I need some information about the measuring mechanism of balancer, Do they use loadcell or accelerometer?
