## Adams/Car FSAE Smart-driver issue

(OP)

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.

As you can see our model, goes out in last corner.

I hope to see your help.

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.

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