Hi dears

There is a gap between two sheet metal body, upper body thickness is 1mm steel and blower part thickness is 0.5mm stainless steel. So in real, two sheet metal bodies are tendency and pre-stressed by three bolts. Now 

 

How can i solve this problem? (Pictures attached)

 

Cross section view of assembly. Main question of simulation is finding spring resistance of purple body in below figure. but

Split the cylindrical face of  the screw shank into two faces at the plane of the light grey part. Then use Bonded Contact to have the lower face of the screw connect to the light grey part. You already have Bolt Pretension, but now you can scope it to the upper face of the screw shank. You can enter either a displacement of < 1 mm or a Force to squeeze the top sheet down.

You will need Frictional contact under the screw head to the top surface of the top part.

You will need frictional contact between each part that touches another part.
