I need to drop a 5 lbs steel ball onto a optical lens from 6 feet up.
Does Cosmos drop test even allow me to do this. can i fix the lens to be my surface and have the ball drop on it???
I am running SW 2009 with all the toys so any advice will be helpful.
Yes...
you need to run a study first ie a static case of wahtever.
then click on the assembly name and add a new study... at the bottom there is an icon with a screw and some nuts, that is the optimization mode.
There are three tabs to fill out. One will link the static case you just ran...
@zekeman: The reason for this test, is I am required by the FAA to actually go out and test these type of shocks on a single working unit to be able to get certified. believe me if it was up to me I would not even bother, as the airplane structure where this gets mounted to has will deform...
As for wind, if you want a quick check.
Find the frontal surface area being hit by wind.
the solve for the resultant force of this:
Cd=(drag force)/(0.5*(Specific density of fluid)8(V^2)*(Asurface)
where,
Cd=Coefficient of drag, you can approximate this to a general shape and get a value...
This is a little late, but it might help some.
I have come to the conclusion that SolidWorks simulation does not care on how much ram you use.
we run a lenovo workstation it has 16 gigs of ram, SSD hard drive, 8mb of L3 cache per core, and I have not seen any real benefits over the dual core...
Guys thank you all for the input, it has definitely helped. I managed to do a combination of hand calc and a full drop test simulation running Cosmosworks.
Since i actually have to test a single unit at 500g's on all 6 axis and then another 100 g 12ms on all 6 axis, I have secured the funds to...
Fex32:
only problem i see is that the SAE rules imply a 300kgs car with a deceleration no grater than 20g's...We did that too...
But I have no idea or the capabilities to get the acceleration or velocity out of this object.
The only lab that does this charges me 8,000 per test, and I...
If you have the funds available:
LightTools. is arguably one of the best software for optics/lighting out there, and is completely compatible with Solidworks, or Catia. it is easy to learn how to use and very powerful..
only draw back is the $16k/year price.
if those funds are not available...
I have no idea if this is the right place to put this.
I have a drop to preform on an emergency beacon. The unit weights 5.1 lbs fully assembled, must be subjected to a 500g 4 ms test. I need to create a bracket to hold this, and have this bracket deform enough to absorb enough energy that the...
