So then the next question is why bother try to do a fatigue analysis based on loads that may be 20% out....
Maybe I'll stick to 3g bump and hope for the best...although the more complicated analysis are always more fun!
Thanks for your help
Measuring strains in arms gets me loads in the arm itself, but the angle at which those loads are applied to the BIW changes, which means I would somehow have to tie the two together, to turn the vectors of the loads into those seen by the body.
PS I like the double integrating idea; like so...
I want to get data that I can carry out fatigue analysis in NASTRAN/MSC Fatigue on suspension components (e.g arm, which I could do as you suggest) but also the BIW. The suspension is mcpherson struct at front and leafspring/axle at rear....
Sounds like you are confirming the conclusion I was...
I am trying to figure out whether there is a way of collecting RLD on a vehicle WITHOUT wheel force transducers (way too expensive) that I can then put into an ADAMs model to extract component load time histories. I am guessing accelerometers are not much use as there is no way of being sure...
