Any active suspension is illegal per ROAR, EFRA, and IFMAR rules. As per the scaling factor, prove to me that it exists in fluid dynamics and win a nobel prize
Honestly though, we run a power to weight ratio in excess of F1, with chassis stiffness that they could only dream of in relation to their damper rates. From an engineering perspective, it is a very interesting design problem.
I have decided to build a shock dyno. I plan to use a real time force measurement device (load cell on datalogger) and get real data. I have a full CNC machine shop at my disposal, and CAD software. This is the best comprise, aside from a 7 post shaker ( which I hope to someday build, someday
).
Fluid mechanics are really, really complicated. Aside from doctorate level math, I really think the only way is trial and error on a repeatable test device.
FYI; the spring damper equation is:
Force= Spring Rate (K, in lb per inch) times spring compression (X, in inches) + Damping Coeffecient (C, in lbs per inch speed) times velocity ( in inches per second)
So
F= KX+CV
The objective of the shock dyno is to find a graph of C versus velocity . I plan to post these for most popular piston/oil combos, but if anyone else has this info, please share
