To measure the forces on the bearings inside a MacPherson shock absorber (strut), I built a simple test model to test the behavior. In the first model I placed the strut vertically (lower and upper mounting point exactly above each other), so the axis of operation of the joints (bearings) were straightforward. R1: [1 0 0] R2: [0 1 0] R3: [0 0 1] P1: [0 0 1]
This model seems to work according to expectations. The normal forces on the bearings matched the ones determined by hand calculations.
In a second model, I placed the strut according to the real coordinates, so it will not be completely vertical, but under a small angle.
The question is now, what should be the axes of operation?
