Hello,
I am using Magic Formula for contact forces in a Multibody Vehicle model (Simscape). The COG of vehicle is free to move about World Frame through a 6-DOF joint, where I kept the internal mechanics (stifness/damping to zero).
I have the following problem using Magic Formula. My body is bouncing to the ground the whole simulaiton time. Looking on the wheel forces through magic formula I get a sinus pfofile of Fz(front,rear) with not enough damping. Also after some time the front wheel Fz is to high that makes the front axle to bounce much and lose contact.
I tried to put some stifness and damping on the 6-DOF joint for Pz or change the .tir file vertical/stifness/damping. Only by giving a high Pz stifness to the joint makes the body move properly, however I see some weird response on the wheel Fz afterwards.
Could you please give me some advice or any ideas to solve that issue?Hello,
