Hello OldEngr63,
Wow. This looks fantastic! Did you have this analysis lying around by coincidence or did you write it up especially for this thread? Either way: I am very happy for your contribution. As soon as I'm back from holidays I will look into this in depth.
Ha :) I like the pragmatic approach, even though the purpose of the tool would be to have a guideline during 3D modelling before the physical packaging exists.
I'll play around with this when I have time and maybe some new bright flash of insight will hit me down the road. Thanks for your help...
I've toyed with this on and off in between "real" work, and by now I've come to the conclusion that what I did was not correct.
I assumed the vertical component of the impact vector to be based on the distance the CoG will drop during the test.
Then I calculated the horizontal component of the...
I'm still missing something. Right now I'm calculating v(impact) as in this pic, based on the fact that the CoG lowers 123 mm vertically during the edge drop test.
The values I use in the calculation come from a situation where the CoG is in the exact middle of the product, so I'd expect a...
Awesome. Thanks! So in this case you can just assume that the vertical component of the impact vector will dissipate on impact? I mean, I know I'm the one deciding how far I want to simplify this. But I want to end up with something that has a foothold in reality. Would you say that this is...
Hi Bystander,
Thanks for helping me! While I can see how those parameters are relevant, I don't quite see what to do with them. As I said, long time since I've had physics class. I made an attempt, mostly based on what my common sense tells me.
At the moment of impact, the CoM trajectory is...
Ok I know this should be easy but it's been a few years since my physics lessons at college and I'm stumped.
I work in packaging. I'm working on a tool that will tell me if a box will fall over when it is subjected to an edge drop test. That means that a block is placed under one edge of a box...
