Hi,

My aim is to simulate a press-in process. The diameter of the Pin is 1 mm larger than the whole.

Modell description:

-          ¼ modell

-          Fricionless supports (shown in picture)

-          Displacement from the Pin:

Loadstep	Time	Displacement x [mm]	Displacement y [mm]	Displacement z [mm]
1	0	free	free	0
1	1	free	free	100
2	2	free	free	100
3	3	free	free	0
4	4	free	free	0
5	5	free	free	100

 

I have problems to interpret the result of the simulation. Specially the result between 1s and 2s I can not understand. I have no displacement, but a very high reaction force (see picture 4). Do you know what is the reason for this?

You should use a lead in chamfer on the pin and the hole.

Also add a blend at the edge the chamer makes with the cylinder.
