Hi guys,

I am trying to do a simulation, where a steel pipe passes through a rubber cone with a hole in the middle (a little smaller than pipe diameter) deforming it as it passes through. My problem is that I add a force to the end of the steel pipe and expect it to move through the rubber cone, however the pipe keeps going forever and I get the excessive displacement error. Is there any other way I can simulate a situation like this and do not have the excessive deformation error?

Regards,

Arkmando

Correct Answer

this type of analysis seems best fit for nonlinear analysis

displacement is available in both linear static and nonlinear static, it is just a restraint where you define a value (0=restraint, X=displacement)

See the reply in context

No one else had this question

fix the pipe at one end, put the rubber in the right spot and maybe fix one end or at least restrain the thing some how not on the bore and somewhere where it won't contaminate your answer. Then appy and shrink fit contact. that will get you the installed response. If you really want the puching force that is much trickier but probably doable. Post a note if that is waht you want.

Arkmando,

I would think that applying a displacement rather than a force to the steel pipe would be a better method. But I am not familiar with how SolidWorks Simulation does this kind of simulation.

bills idea is a good one as long as you don't care how the seal/cone looks like as the pipe is dragging through it

also make sure you're working in nonlinear

and finally, like Jerry suggests, the best way to do this is to displace and read the forces required to displace it

Hi Jared,

What type of study should I use to enter displacement instead of a force?
