I'm trying to automate capturing resonance of a material. My current setup is this:
I have a plate with magnets attached to a material. There are coils around the magnets.
I have an accelerometer attached to the plate
I have a sony 5 channel amp that gives voltage to the coils which then excite the magnets which excite the accelerometer.
I read the acceleration output on multimeter.
I have an analog Global Specialties function generator that I sweep with
I find the frequency with the FG, at the peak accelerometer voltage, and I get a resonant frequency.
In addition, I have:
I have a NI-9174 with 4 slots.
I have a NI-9104
I have a NI 9215
My question is. Can I take the analog FG out of the equation and use labview to produce a sinewave which will then be powered to the coils? I want to automate this process where I can set a schedule and it'll sweep and find my peak acceleration.
I'm A CLAD at best ,so a starting point would be nice. First, do I have the capabilty to automate this with the hardware I have? If I do, how would I go about setting up a virtual FG to replace my old dinosaur analog FG?
I'd appreciate any input! Thanks guys.
I have yet to get an AO module...my typical frequency range is 15-120hz while inputing 9mv-20v. The analog FG I have is a Global Specialites 200khz 2001a. Seeing that I'm trying to do this without it, I didn't think that was pertinent.
The FG has a max of 10v. The amplifier gives me the other 10v I need. So really I need to output 10v to my amp from the FG.
