Hello, I’m posting here for the first time.<\/span><\/p>\n

It’s my first time using Ansys Static Structural, and I’m trying to check if the battery container is safe enough through hard condition.<\/span><\/p>\n

Assumption 1: The boundary condition is x: -40G(-392.4m\/s^2), and fixed support for mount holes.
Assumption 2: There is about 2mm margin between surfaces and segments.
Assumption 3: The segment can support stresses or forces through surrounding surfaces.
Assumption 4: The segment is rigid.<\/span><\/p>\n

I modeled the surfaces of the container as 2D, and the segments and mounts as 3D.<\/span><\/p>\n

I have to assume the segments to be rigid, so I set the mounts, outer surfaces, and the inner surfaces flexible, and the segments rigid<\/strong>.<\/span><\/p>\n

And I set the mounts and the outer surfaces “Bonded” each other<\/strong>, and the +x surfaces of segments(contact) and the -x surfaces of inner surfaces(target) “No Separation” each other<\/strong>(by assumption 3).<\/span><\/p>\n

Finally, I gave fixed support for mounting holes, and acceleration x: -392.4m\/s^2.
<\/span><\/p>\n

Then I got the results, and I thought something went wrong.<\/span><\/p>\n

In total deformation, the left two inner walls seems to have no displacement at all, but only the right wall has 6mm deformation.<\/span><\/p>\n

I think my settings can’t simulate my assumption properly, especially the interaction between segments and inner walls.<\/span><\/p>\n

I’ve tried to modify the settings, but I can’t get it.<\/span><\/p>\n

I uploaded the image about my settings, and I would really appreciate if you could help me solve this problem.
<\/span><\/p>\n

Thank you very much.<\/span><\/p>\n
