'Overpull Car Hinge' simulation project by brdelatti


#1

I created a new simulation project called 'Overpull Car Hinge':

Applying an overpull angular displacement on a par of hinges.


More of my public projects can be found here.

Hi everyone! I have done here an overpull simulation of an automotive Hinge, like the ones used in car doors.

The CAD model was downloaded from GrabCAD member Karem El Shemy.

The geometry was a bit simplified and then uploaded into SimScale Platorm. It was meshed using parametrized tetrahedralization.

The mesh is shown below.

Four contacts were created. 3 of them as sliding contacts and the other one as bond contact, since the Pin was considered bonded to the bigger Hinge, the one which does not rotate.

It was used the plastic curve of the thyssenkrupp MHZ340 steel.

The bigger Hinge was constrained as fixed support on its holes inside surfaces.

The Pin was constrained as a deformable remote displacement.

And the smaller Hinge also as a deformable remote displacement but with a prescribed function considering a rotation of 2 Degrees on the Z axis regarding the axis of the Pin.

The simulation was performed by 16 cores and took 19 minutes to finish.

Below you find images of displacement and Von Misses stress.

We can see that plastic strain has occured since the yield strenght (344MPa) was exceeded. I don't kow if the material should be changed or the model can be improved. Or even the 2 Degree forced rotation condition is too much for this case.

Really nice post-processing images @brdelatti!

Looking forward to see more from you in the future :slight_smile:

Best,
