Thank you guys! The part yields but does not fail. The design was correct, It was indicating failure because I had my material properties incorrectly saved.
I have an extremely fundamental question. The value you obtain from weight scales, is it in N? So if I weighed the IV bags on a weight scale and I get 1.2, does it reflect kgs or N?
I suggested SS just for the hooks. The hooks welded to a SS insert that just bolts in to AL pipe(the IV pole). They just like AL because it is lighter but for such a small component it doesn't make a difference.
I will look through the standards but you are right, I have not seen IV bags...
Haha yep. I mean getting hit with a 1.2kg bag in the middle of a crash no matter how soft the projectile, is not ideal let alone getting hit with a radar.
It is easy to overlook because some of it seems counter-intuitive.
Also, do you reckon my reasoning is correct? I think the plastic bag...
I just realized that the bag restraint will fail before the AL hook fails. I have been so worried about just applying the load to the hook that I forgot the bags are made of plastic and that will fail before the hooks fails.
Hi 3DDave
Thanks for the quick reply. There is no heat treatment.
The standard that I am using stipulates 20G factor for static loads as the system is going to be used in ambulances and fixed winged aircrafts. Any load that goes on to the hooks is simply multiplied by that factor in the...
Hi Guys
I am working on a design for an IV pole hook which is required to carry 1.2kg bags. The challenge is to allow for a 20G frontal impact load factor. The design uses AL 6063-t6 rod - 6mm. The FEA indicates failure when the load moves slightly away from the fixed point. It passes when it...
