I kind of expected the answers you just gave, which is appeciated. I knew my ideas, were half complete as they are based on just watching some of my coworks and fellow engineers do structures and fatique of our flight test aircraft. I do have access to matlab.
For my case, we are purely looking at shock designs (custom in development ones... side project for as I am an electrical guy with tons of aircraft testing experience and a huge love for all things mechanical from racing to engine building which I do.)
I had thought of linear transducers for this instead. I found 5" travel plunger style pots which when mounted near the pivit point of the control arms would provide enough resolution (with the known suspension geometry), we could sample them all at the same time and then just use time to determine suspension accel and deaccels for determining shock survivability. However the part that really matters is while we could determine shock travel and stuff, we can't differentiate from bumps to surface contact to determine if we are faster and hold more lateral grip thru a turn of uneven surfaces. Yes we have start stop times, however its not like a road track where you are more consistant in driving because a lap may only take 1-2 mintues and the surface doesnt change.
Here the variables are huge, so we have to look at things differently.
