Longitudinal excitation methodology(at contact patch) in Adams Car

Tinu

Hello,
 
I am looking for a longitudinal excitation methodology(at contact patch) in Adams Car at vehicle level.Since GAA can excite only at the wheel center I am not able to use it,more over I am using a displacement function to excite the pads.I have tried to change the vertical test rig pad transnational joint orientation to horizontal,simulation is working fine but I am not able to get the expected behavior.Can anyone suggest how to do the same.
 
Regards
Tinu

    What tire model are you planning to use that is accurate for standing still tire?
    I usually use the GAA with a longitudinal force and a braking/driving torque at the wheel center. f you have varying normal load and therefore varying tire radius, you can always take that into account when calculating the torque.
