Has anybody heard of this being done ?
I am involved in a project in which we are installing a number of antennas and external sensors on an aircraft. I have one particular installation where our customer wants us to take bird strikes into account. The installation is a combined...
Mainly, what loads will be applied to the various equipment racks, etc, when the aircrew grab them, lean on them, or bump into them.
I've seen references to Boeing D6-55441, which I gather is their guide to cabin furnishings like tables, etc, although I've never actually seen a copy. I've also...
Does anybody know a good reference for this ?
I'm specifically concerned with military transport/Spec Ops aircraft, that will have big people wearing bulky flying gear moving about the cargo bay. There are various equipment racks and other furnishings in that cargo bay. It seem likely that...
Thanks to everybody for the info.
My problem is further complicated by the fact that some of these panels are lying on a rigid floor, and are being deflected out of plane. Even to do a static analysis, I'd have to do it nonlinear with contact surfaces, etc.
It looks like a plain old...
I have a certain amount of experience doing modal analyses and other vibrational analyses on metal structures using NX NASTRAN. However, my company is evaluating a proposal to do modal analyses on some composite parts.
Their material is highly nonlinear, basically plastic. Can anybody...
I'm doing an analysis of two mating parts, in which friction plays a prominent role. Both parts are aluminum.
All the data sources I can find show that the static friction coefficent for aluminum-on-aluminum ranges from 1.05 to 1.35. However, the dynamic coefficent is given as 1.40.
Here's a...
Can't tell - Unfortunately I didn't know to look at the time, and my photos don't show it clearly (I was at a site survey looking at other things, and this was a bit of an afterthought). However, I will pass that question on to the folks at shipside.
They are disbonding in several places around the door edge, but do not seem to have a "favorite" spot.
Then again, my sample size is pretty small (3 out of a fleet of 20-odd aircraft).
Not sure about the primer, will check.
I have a problem with an aircraft door seal that's disbonding. The door is a composite door with a rain seal around its outer edge. The current seal is an AMS 3195 silicone rubber strip, bonded to the door with MIL-A-46106 Group I Type I silicone adhesive. I'm not an expert on adhesives, but...
Thanks for the responses.
My coworker will be doing most of the FEA work. He's pretty well qualified on Solidworks and COSMOS so no worries on that score. However, he has no experience on NASTRAN, so we don't really know how they compare.
I'm more interested in how the FEA actually works...
Howdy folks, new guy here. I hope this is the right place to post this, if not, please accept my apologies.
I don't know much about COSMOSWORKS. Can anybody clue me in on how it compares with NX NASTRAN ? Is there any particular reason to favor one over the other ?
I am an aerospace...
