How to calculate stresses in knuckle due to lifting lug

How to calculate stresses in knuckle due to lifting lug

How to calculate stresses in knuckle due to lifting lug

(OP)
Hi Colleagues:

It is a habit to put lifting lugs in head knuckle but unfortunatelly it is so difficult (almost impossible) to find example works related to how determine stress in this zone. Could anyone explain me how to perform this calcs without using FEM? I would be very appreciated.

Thanks in advanced.

RE: How to calculate stresses in knuckle due to lifting lug

I would first check, dose lifting load greater than. P*A, if not, good, the head will not fall off.
Then I would approximate a tangent angle of the knuckle at the joint, and and set it plane to 0 degrees, and offset the load direction by the same amount, then analysis the lifting lug as a normal vertical one.
my 2 cents

Luike:
Show us a well proportioned sketch of what you actually have, with dimensions, thicknesses, sizes and loads, we can’t see it from here.
