Bondary conditions (rotation without translation)

[Tpintar]

I am relatively new to solidworks simulation so maybe I am asking something quite obvious but any help would be appreciated. The model I am working on can be seen in attached image. I am trying to do a linear analysis, taking into account uneven supports.



Load is continuous, but indicated with one arrow for direction only

On the left side no translation is allowed, and rotation is allowed only about support axis (hinge)

Right side should allow translation along longer axis of construction, allow rotation about support axis, and additionally should account for "a" degrees torsional deflection.


The problem I come up with is when I set up a constraint I cannot have the support and torsional deflection at the same time. I can set up deflection angle, but I have to allow translation thereby loosing support from that side of construction.

Any help in the right direction would be helpful.

Use a virtual wall to support the right side.

I tried putting inclined virtual plate, and keep loading vertical. But the results seem odd, and I am uncertain if that is the correct way to do the analysis.

Although maybe I can apply rotating boundary condition and put an aligned virtual plate under it. I will try and be back when I have some idea of the results.

So PeteDB provided the right answer, I would just like to ad one note: setting the virtual plane with an angle of inclination will yield results which are a bit off due to contact in a single point. I got better results by making a virtual plane which starts off level, and progresses into the incline with a gentle radius. This way there are no stress concentrations. You just have to be carefull to keep the straight and radius part of the plane short enough so they don't mess with your results.
