Static simulation fails while real product succeeds

Dear Forum,


I'm running into a problem using solidworks simulation. To be very clear I'm not a professional using static simulations. I know the basics.


A coupler plate for some machinery we have here needs to lift 2.5 Tons. To get a proper certificate it needs to lift up to 200%, meaning 5 Tons.

It did this without any problems or deformations in the product. But when I try to simulate this in Sw, it shows that it should fail. The biggest stress areas Sw shows are logical though.


Attached is the product.

Below some screenshots:

The hoist ears are welded on the bend plate. Can this be the issue?


I would be very happy to get some advice from you guys on my problem.
