Hi All,
I am trying to obtain the transfer function Y(s)/F(s) on a basic car suspension. Attached is the page of my model but I don't believe it to be correct but I am not sure what I am doing wrong. Please Help!
Model: 2 Degrees of Freedom (Car mass 1st DOF, spring and damper fused at the bottom 2nd DOF).
I imagine this model to be simply a force being put where the fused portion of the damper and spring which should oscillate, but not according to my transfer function, so it can't be right. Typical models use a tire mass or suspension mass, but let's suppose that we simply have the chassis mass and put a force at the fused point (considered massless). I can't figure out what I'm doing wrong.
Thanks for your help. I know I can count on you guys.
