plastic clamp on curved metal bar

SteveMeltonSteveMelton
Contacts used a number of places. Installation is to snap clamp on to bar separately and then install the arm. Arm will support 0.5 lb at the tip with .2 in deflection.

    looks great. how did you manage to get such a good mesh generated?

    I agree with Dave, very nice model

    that's automesh of a STEP file with x2 mesh refine using paint at the arm to clamp contact. quick and easy. solves in less than 30 minutes. a couple of things going on here, one, the arm to clamp interface and two, the peeling of the clamp from the bar.

    Hello Steve.

    “a couple of things going on here, one, the arm to clamp interface”.

    ¿Which kind of contact are you considering.? I think you didn’t merge nodes as it looks like a free clamp that could open or slip but ;
    ¿Isn’t a phisical gap between the two components needed for convergence?.
    ¿How did you managed? ¿Only compression maybe?

    Any information you could provide would be appreciated

    3D non-linear CCX. Nine contact surfaces. Each part is separate, clamp, arm, pin, bar. the pin has a .002 inch gap on the diameter, others are no gap. start with a small load. if the deflection is too much it cannot converge.

    Thanks for sharing your experience with us.

    spot on deflection, validated! :)
