I want to do the buckling analysis of the attached assembly. The flap is hinged at one edge on the longitudinal side of the flap and is to be lifted by two jacks at extreme ends on the opposite side of the hinge.
I'm not sure I understand your problem. If it is hinged on one side, then when you apply a force (by the jacks) then you will get rigid body motion. Since buckling depends on extracting eigenvectors, your model will have a mode at zero hertz (rigid body motion). What force or constraint resists the rotation of the flap? If you are trying to fix your model by balancing forces, be careful. Numerical round-off almost certainly assures the forces won't be balanced. This is one problem.
Secondly, you have interference between some parts in your assembly. I'm sure this causes problems with meshing. Try merging your assembly into a part file. Mechanica does this anyway with touching constraints. The only caveat would be if you need different material properties for the different parts.
Why are there shell idealizations in the model? I would use beam elements. If you try doing this with solid elements, good luck.
I will try to build a beam model, but in regards to your 'frustration' to the lack of response; this is not PTC customer support. Maybe they could help out with some more training classes. We help each other out in our spare time.
I delighted to see someone reply to my posting. My friend I know beam idealization is the best solution. But what I have is the book on pro/Mechanica by Roger Toogood which is too basic and I have heard beam idealization of curved beams is not simple.
hi isar . can u plz help me to find the life of the newly developed equipment. the equipment is used to lift the concrete pipes of 7.2 tonns load. my company has requested to perform the life cycle calculation.
