Adams/Car FSAE Smart-driver issue

[ascalom]

Hello everyone !

We are trying to complete one tour track with our fsae model for bachelor project. We design just front suspension and build and assembly with fsae_2018 template. I have a few question that we can't achieve anthying.

1) As you can see in our model, we think there is a problem with anti-roll bar and rocker joint. Can you help us ?

2) With these configurations in Smart-driver;

We have a problem with cornering in the last-corner.

---- START: ERROR ----
The integrator is unable to proceed. Possible Causes:
(1) The accuracy required for the numerical solution can not be attained.
Relax (increase) the value of the acceptable integration ERROR.
(2) Incompatible redundant constraints, a lock up, or a bifurcation
situation. The latter two indicate a mechanism design problem.
(3) The system includes a zero (or relatively small) mass on a part with
an unconstrained translational degree of freedom.
Make sure you have mass on all parts with translational degrees of freedom.
(4) The system includes a zero (or relatively small) inertia on a part
with an unconstrained rotational degree of freedom.
Make sure you have inertias on all parts with rotational degrees of freedom.
(5) An Adams element has a function expression that equals exactly itself.
For example,
SFORCE/id1,I=id2,J=id3,ROT,FUNC=SFORCE(id1,jflag,comp,rm),and
DIFF/id4,IMPLICIT,IC=0,FUNC=DIF1(id4).
Similarly,
VARIABLE/id5, FUNC=VARVAL(id5)*TIME
equals itself at 1 second. Avoid setting an Adams element equal to itself.

anyone can help ?

Hi ascalom,

Your model suspension owns wrong joints and wrong orientation of joints. Think twice.
