Abuse Loads
Abuse Loads
(OP)
Hi guys,
does anyone know something about "abuse loads"?
Can you suggest me some references or give me some tips how to quantify them?
Thanks!

RE: Abuse Loads
we here use a 200 lbs ultimate load applied to the tip of an antenna as a means of "showing" that our antenna support structure is robust (= stiff) enough that we won't have vibration issues with the large VHF blade.

Debodine, what kind of load and entity do you consider for the interiors?
RE: Abuse Loads
The one clear example I can positively recall was an assumed abuse load of 300 pounds in a downward direction for an overhead LCD monitor. The scenario was that a passenger would grab the monitor and hang from it. The airline that was our customer at the time reported that as a true incident that occurred on one of their flights, and we now regularly use that assumption for LCD monitor installations since that time.

B.E.
The good engineer does not need to memorize every formula; he just needs to know where he can find them when he needs them. Old professor
RE: Abuse Loads
1) step on ( so far the best values found was 1,5* weight of large operator ( Caesar data) 1.5*250lbs
2) Lean on Fraction of the 250lbs (probable 50% still to be defined)
3) Bump into (Still to be defined)
4) Grab (ex handle)(Still to be defined but probably max weight + safety factor)
I did not see the SAE reference mentioned in the treads, any hint?
The idea for us is to have some generic guidelines for the 4 categories and not analyse in detail each situation ex: the angle of the applied load.
the risk assessment need then to be factored in. Having a ground operator falling Vs breaking a small peace of equipment is different
Of course we want to avoid overengineering by adding too much weight on the A/C.
RE: Abuse Loads
So for things that won't be stepped on or are nota ready grab in an awkward access area, or subject to passenger abuse I've seen 50 lb as typical.
