Tension Fittings Filler Pads - Throat Pads - thread2-297984

Tension Fittings Filler Pads - Throat Pads - thread2-297984

Some good work on this thread by edbgtr in 2011, thank you.

I am trying to use the calc method for a filler pad on angle and channel tension fittings which have been manufactured undersized. Hence they need throat pads applied - currently tentatively sized based on a nominal efficiency factor being applied to the end pad thickness (used in a standard tension fitting calc, as per Lockheed, Bombardier or similar).

The Appendix V supplied as a attachment derives an eqn for P/F where P is the load applied to the fitting flange and F is the load in the throat pad? It seems that having obtained P/F for my own EI (throat plate and flange), l then use the P in a standard TF analysis. The F is used to locally stress the throat plate for bending.

Please confirm this is the intention of the P/F eqn., or have l missed something?

Do you happen to have a copy of the Bombardier manual? I have been searching for it.

The BM methods are proprietary and hence copyright, l doubt if you will get a copy via a request on an open forum.
