Clip-spring insertion
Clip-spring insertion
(OP)
Dear friends,
I'm trying to do very basics, insertion analysis of a ring in to a shaft groove, via prescribed displacement conditions to know the force required, but until the ring reaches the grove the job is aborted by a classic convergence problem, " Time increment required is less than the minimum specified" ... Now I'm stucked because I try different time increments and element types too, with no success convergence, please take a look at the *.cae or the input file, any suggestion will be appreciate.
Best Regards

Explicit may be more appropriate as curlyq recommended if you want to capture the dynamic affects of this.
At the edge of the groove it looks like there is a fillet or a chamfer. Increasing the fillet especially will aid in the sliding contact not snagging on the corner.
I hope this helps.

The clip doesn't go all the way to the groove though, I am assuming that this is the way you where you wanted the model to end.

Thanks a lots for the time you took to read it, I also think same as you, rigth now I'm trying to run it into Explicit.
I'll keep you informed

Thanks for the sggestions job running, you're right the groove will be reached at 6.5mm not 6.0mm as I put in the prescribed displacement.
I'll try also in the explicit way
