Suspension spring analysis

[tejras]

Hello,

I've been working on modeling a scooter. now I'm on the stage where I need to analyse the suspension systems I've designed theoretically on paper.

well, I know the procedure for structural analysis ( as done on chassis) but the suspension is a flexible body that might need different solver in Nastran (I don't know exactly).

So the question is how to analyse this system on Nastran accurately? I'll be thankful for your help
