I am currently working on a trolley structure to bear a heavy machine. I am also new to Patran and adding contacts to analysis.
* I used 3d solid mesh with automatic calculation for the whole.
* The image below shows BCs. The weight of the heavy machine being transmitted <0 -F 0> to the structure by the four plates and the other 4 plates below the structure is being fixed T<0 0 0>. These constraints are given on the plate faces.
* There are a total of 20 solids in the image and in real, all the solids of the structure are welded, also all are of same material. Hence i made 20 deformable bodies and made a glue contact wherever necessary in the contact table.
* When i run the analysis and see the results it doesnt show any vonmises or stress tensor, but just contact stresses, and few other stuff. there was no deformation.
I think that the contacts must be a problem or the boundary condition. Since the stress and deformation were not calculated i assumed that the force is transmitted directly to the constraint and is normalized. Can anyone help me finding the solution.
Thanks a lot in advance.
