Vaildating a tri-axial accelerometer

[Branny12000]

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

.In order to validate your accelerometer, you need to collect data from the device at different frequencies and compare it with the expected acceleration values. To do this, you should time-align the two traces so that the data points correspond to the same time. You can then calculate the difference between the expected values and the readout from the sensor and use this to determine the accuracy of the accelerometer. You should also take into account any potential sources of error that could affect the accuracy of the readings, such as temperature or vibration. Finally, you should also consider any other factors that could influence the accuracy, such as the accuracy of the wheel or the resolution of the sensor.
