I've been having some trouble with this problem for a while. (Its not a homework or coursework problem)(adsbygoogle = window.adsbygoogle || []).push({});

Its a part of an experimental set up that I'm building and this is a simplified version of it.

I have a rigid rod which is hinged at a point and can pitch or heave about that location. There are 2 dual axis accelerometers mounted at either ends with the one at Leading edge inclined at a known angle theta.

I need to calculate the real time angular and vertical displacements from the accelerometer outputs. The angle is the most important parameter that I need.

The angles are not small, so small angle assumptions does not work.

The motion of the system is quite random, and its a non-inertial frame of reference. (This system is quite similar to the suspension system modelling for cars)

I'd be grateful for any help or insight regarding the problem.

Thanks
