Calculation yaw moment with 2 accelerometers

Calculation yaw moment with 2 accelerometers

Calculation yaw moment with 2 accelerometers

(OP)
Can anybody help me with the following:

I'm trying to calculate the yaw moment of a racecar. To do this I have an accelerometer on both front and rear axle available. Can anybody help me work out the maths?

Thanks!

RE: Calculation yaw moment with 2 accelerometers

Do you mean the yaw velocity?

Are your accelerometers in the y axis (lateral?)

If so yaw velocity = integral (yaw acceleration) dt

yaw acc= (AyF-AyR)/wheelbase*constant

The value of the constant depends on the units of the accelerometer and your desired units for yaw velocity

Cheers
