Contact analysis of lifting pin in hole

Contact analysis of lifting pin in hole

Contact analysis of lifting pin in hole

(OP)
I am trying to set up a contact analysis between a lifting pin and the inner surface of the lifting bracket hole, both have different diameters.

When setting up the connection 2 contact areas must be defined. Is this the contact area before material deformation begins? Bearing in mind the initial contact point at the tangent of 2 cylinders of different diameter will be infinitely thin and will only become an area with thickness when both parts begin to deform.

Has anybody come across a similar problem and if so how was the contact area set up?

Inputs are as follows:

Radius of pin - 60 mm
Radius of lifting bracket hole - 62.5 mm
lifting load - 1 000 000 N

corsa007,

I am pretty sure this is a common form of contact similar to a bearing analysis.  Here is a document posted in the PTC communities forum that really helped me out and hope it helps you out.

Good luck,
