How to simulate the stress on adjacent pipe racks when the clearance between them is extremely small?
Thread Content
I have a question for everyone: A 1-mm thermal deflection of the support in the model results in very high stresses on the adjacent pipe supports (tens of tons). But based on experience, we can assume that in reality this pipe support has not become empty; then, is it possible to determine the actual stress on its adjacent supports (which should not be that high)?
Try using a spring to see if it’s possible to determine the forces acting on adjacent pipe racks
Is the simulation with springs the same as the actual situation?
Lift it up, I hope someone can help!
I’m not too sure about this either; I’ll have to give it a try
If you’re sure it won’t become hollow, then change the bracket at the hollow area to a Y shape.
Are you saying that by restricting the displacement of the hollow area and subjecting it to forced forces, the stress on the pipe rack becomes closer to the actual conditions?
This cannot guarantee authenticity. The force at the support is infinitesimal or 0; in such cases it may not come loose, but the reaction forces of the entire system will be redistributed.
Thank you! Can it be understood that, in this case, it is difficult to use software to simulate a situation that is close to the real one?
If the structure sags at the adjacent supports, the void area will be supported; the stiffness of the structure can be entered in the stiffness field for those support points
Thank you! If structural stiffness is taken into account, does that mean all pipe racks need to be considered?
