Vaildating a tri-axial accelerometer

  1. Jun 16, 2014 #1
    I was wondering if you could help? I am attempting to validate an accelerometer. I have a triaxial accelerometer and placed it on a wheel which goes at various frequencies from 1 to 3 hz
    Am I right in thinking that I would EXPECT the acceleration in z to be 1g

    and then in the x and y plane I would expect a read out of acceleration in X(t) = -((radius of the wheel)*2*pi*frequency) * (cos((2*pi*freq)t)
    acceleration in Y(t) = -((radius of the wheel)*2*pi*frequency) * (sin((2*pi*freq)t)

    however how can i compare these with my readout from the sensor and how is the best way to report accuracy. I'm confused as surely I will need to quite accurately time align the two traces?

    Many thanks in advance for your help
