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.
Cheers,
Boris
Hi JM Van Oossanen,
Okay, just a couple of things to point out as a Rigger which I have past experience in.
Why would you have this 'cut-away' present as it will only present itself as a weak point in the overall lifting structure?
Is the hole between the lifting fixture necessary as it appears that the corners are what may be showing the weakness?
But most importantly, what happens if you try your design with your lifting fixture running parallel to your lifting lugs?
Or, better still.....................
Just as a side note, although it does happen, a certified lifting device will very rarely have any holes, cut-outs, perforations or such unless they are for a specific purpose.
Just some ideas above for you to ponder.............
Dave.
