Are you interested in learning more about vibration and alignment tools & testing for machinery maintenance
This poll is to check your interest in industrial equipment alignment and vibration testing. We are trying to determine if this is an area where the community has an interest and whether we should offer more content and information in these areas.
Vibration analysis is quite interesting, different type of vibrations can indicate different kind of problems. Some time ago I made a Labview/python program to perform realtime order tracking (https://en.wikipedia.org/wiki/Order_tracking_(signal_processing)). The nice thing about order tracking is that it doesn't depend on the rotational speed and it ignores non rotational unrelated vibrational noise. Basically when you do order tracking you convert a time series into what could be called an "angular series", that is, instead of keeping measurements at every dt, you keep them at every dtheta. So in the case of say bearings you know that their balls roll at a defined factor of the axis rotation speed, through fourier analysis then you can actually measure vibration caused by bearings balls.
