How to rotate and translate a part during run time simulation?

0 Maziar R over 7 years ago

Hi Tuan,

You can make use of the Adams Solver Command

MARKER/ID,QP=...

to move a part around provided that the marker is the anchor/reference marker of that part. You also need to make sure that the dependencies are all properly addressed.

Check out the attached model. MARKER/2 which is the anchor marker of the box is used to move it around at time 0.2 seconds. However, the dependent object JOINT/1 whose ground marker is MARKER/4 should also be moved. As a result, MARKER/4 is also moved to address the dependency issue.

Thanks,

Maziar

Otherwise a GCON would be my favorite pick.

Thank you, Maziar !

I see the part II moves as expected.

My problem seems a little bit more complicated.

I need to move a part based on of the translation vector and rotation matrix of another part in the last successful integration step.

Some thing should relate to subroutine, right ? But I have never tried subroutine and don't know is this possible to do my idea.

Any suggestion?

Well this is what a GCON does, but I won't type it a third time.

@Martin Kieltsch I looked at some examples of GCON in this and old forum. I see GCON could be nice way to constrain object.

However in my situation, I need to input the previous displacement of another part which probably could't get using acf file, but might be with subroutine .

@Maziar Rostamian Would you mind suggesting any subroutine I could use to move a part per integration step ?

I have just started with Adams but got more experience with Marc subroutine.

My thanks!
