BC's Acceleration Ansys Workbench

[lavecchiasignora]

I have a structure which is attached to slings (4 slings). The structure is then lifted through the slings. I apply an acceleration on the structure upwards in Ansys Workbench but I am not sure about the boundary conditions. Should the lifting holes ( all 4 of them ) be set to fixed support or just locked in the vertical direction ( same direction as the slings) ?

Thank you

I'm not exactly following what your problem is; perhaps you could post a picture?

with flexible cables and hooks free to aligh with the tension, they are considered pinned supports
