Hello,

My question does not relate directly to mechanical engineering but I'm
hoping that someone with a good knowledge of Ansys will be able to help
me.

I am trying to model an electric overhead travelling crane and am
having a little trouble with the contact between the crane and the
support beams. The effect I am trying to acheive is similar to that of
a car on the road i.e. the contact is compressive only and when tension
occurs the wheel lifts off the road/beam.

I am currently using a 2D 2Node contact element with a height between
the nodes of 300mm; the lower node being the level of the support beam
and the upper node being the level at which the loads are applied to
the crane. If a sufficient horizontal force is now applied to the crane
at the upper node level the wheels at one side of the crane should
lift.

I'm sure my explanation could be a little better but hopefully this
will do as a starter.

OK, so my questions are then, what is the correct contact element to
use because I am having trouble acheiving the desired effect? and am I
trying to model the element correctly with a height of 300mm or does
this sound odd to you regular Ansys users.

I have a .lgw file available if anyone would care to help me out, any
advice would be much appreciated.

Kind Regards,

Lee
