Kinematic coupling- selection

Kinematic coupling- selection

Kinematic coupling- selection

Hello All,

May I know the option to select one of the generated kinematic couplings from bunch of them. right now I am using interaction mode-constraint manager for viewing and editing. I am looking for easy option for selection.

I would appreciate your help. Thanks in advance.

Kind regards,

You can also use Abaqus Object Manager plug-in. It will let you manage various features of the model, including interactions. It can be downloaded from the Knowledge Base.

RE: Kinematic coupling- selection

Thank you FEA Way. I have one more question for you regarding reference point. I am adding rigid coupling to a shaft end face and reference point in a space. As I want to constraint the reference point to avoid the rotation about shaft axis. shaft is meshed with solid elements and having 3 DOF. what about the DOF available for that reference point, weather 6 DOF or 3 DOF? I am sure that it has 6 DOF but want to make sure once again.

Thank you and have a great week end.

Kind regards,

RE: Kinematic coupling- selection

When defining coupling and selecting "Constrained degrees of freedom" leave default settings (6 DOFs constrained). Then when you apply BC to that point, the number of constrained DOFs depends on the specific case. Is it typical stepped shaft with two bearings ? If yes then you should apply 2 couplings representing these bearings and for the first one fix all DOFs except for axial translation while for the second one fix all DOFs including axial translation. Rotation about the shaft's axis can be blocked at the keyhole instead of doing this at these couplings. But if you want to constrain only the end face for some reason then you will have to fix all DOFs to prevent rigid body motions. However I recommend the first approach.

Thank you so much FEA way.

White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
White Paper - The Other Side of Design for Assembly
Assembly level constraints need to be satisfied before the design can move downstream. This white paper will go through the various assembly level issues, which need to be tackled by various organizations on a regular basis. Know more about DFMPro, a design for assembly software. Download Now
