Rotation of a part after deformation

[srimanishreddy]

Hello Guys,

I am presently working on Abaqus to analyze contact and pressure on a revolute joint(hollow cylinder-bushing over a solid cylinder-pin) when it is subjected to dynamic loads.
1.The pin is attached to the pin plate with a surface-surface explicit hard contact interaction and so is the sleeve to the sleeve plate.
2.The sleeve slides on the pin with a tangential-penality explicit interaction.
step1: To pull the pin plate with 20N force to achieve the pretention in the joint. To do this, I have fixed the sleeve plate edge and applied the pressure BC to the pin plate with the option 'total force'
step2: The pin plate is rotated with the pretention still on to analyze the contact pressure on sleeve during the motion along with loads

problem: I am able to achieve step1 but when the next step starts solving, Abaqus exits with an error. But I am quite sure the problem is with the rotation(BC's or others which I am seeking help for) as the model starts to rotate in a weird manner.
I am attaching the python script for reference to understand the boundary conditions which I gave.

The script isn't working for me. It can't find the referenced sketch at line 158.

I've seen that the amplitudes do not start a zero. You should fix that and check if that makes a difference.

Thanks for your reply Mustaine.
I am attaching the files.I have changed the amplitude chart and still no luck.

There are multiple rigid body modes possible and the little forces with contact+friction do not prevent the rigid body movement.
