%*Please see images above*% Hey, I am trying to model the relationship between tire generated forces (at the contact patch) by inputting loads into the suspension arms (what i would theoretically be able to measure) to predict the corresponding forces at the tire. Unfortunately, this current model gives me 0 force (by trying to model a road on which it is incident). Am I messing up dependencies, is there another way to do it? What joint should I be using? Thanks, Ps: i managed to have a working model for inputing tire forces and measuring suspension loads, but cannot figure out how to reverse the process.
