I am creating random vibration test specifications for multiple units following this reference https://femci.gsfc.nasa.gov/random/randomtestspec.html
is there a software that implements automatically these rules in guideline 3 of this reference?
it becomes useful if you have to create multiple...
How to evaluate the forces at RBE2 and RBE3 interfaces?
Is it possible to do it without a spring or beam element in between?
What I have is
CQUAD4 - RBE2 - CQUAD4
and
CQUAD4 - RBE3
My solidworks suddenly became very slow, even if I am starting a new part, or clicking anything, for example "Front Plane",
it makes my power usage to instantly spike to "very high" (image attachment)
I have restarted the computer, I have enough space in the disk, and I don't see what could be...
Running a frequency response in a structure and plotting the accelerations at specific locations, from 10-100 Hz
The resonance modes in these locations are in the range 60-80Hz, but the maximum plotting the maximum accelerations, these maximum appear at 25-35Hz, which is not expected. Anyone...
See attachment picture
I want to place orange structure in the blue structure.
1) The orange structure was analyzed, isolated, with a specific random input. Accelerations on the structure were extracted.
2) The blue was analyzed, together with the orange, and with a similar random input of the...
What is the typical procedure to ensure the following:
assembly a box made of 6 honeycomb panels
what would be the connecting element between the panels?
how to make sure the core is not visible?
I read magnesium is soluble in aluminum
is it reasonable to have one part of aluminum in contact with one part made of magnesium?
Would I have degradation of the magnesium part? corrosion? ...
At what distance should the center of the gear be to have a perfect match? -I am including the 2 gears in a CAD, but need to know which position I should place the center of the gearshttps://files.engineering.com/getfile.aspx?folder=7a74cbbe-caed-4129-ba7d-f9a8c6e1d760&file=Capture.JPG
For a bracket being design for space applications
where do the structural requirements come from, for example
frequency higher 120Hz
acceleration x,y,z 20g,20g,25g
random and so on
where the exact numbers come from? because the documents I searched are generic
What is the criteria to decide if it would be better to test (or not) an structural item for the following tests:
[ol 1]
Sine testing
Random testing
Shock testing
[/ol]
Typically for structures 2. Random is tested
But sometimes people decide that it is safe to not test 1.Sine, and 3.Shock
What...
What are the properties that define if an arrow can pierce through a wall?
I guess the material properties, as ultimate strength
and the geometry - thickness of the wall, sharpness of the arrow
but given particular examples
arrow of steel
wall of titanium, 10mm thick,
how can we theoretically...
For plane elememts, I can choose Laminate, Plate, Plot only, Plane Strain...
Any way to generate a property for 2D laminate elements in plane stress state?
Hi all
by using custom tools > post processing > nodes move by deform
all nodes will have the coordinates of the deformed model.
is there a way to have the nodes at the previous, non-deformed, coordinates?
thanks
how to do a linear extrapolation of stresses from integration points to the nodes in wedge element (6 nodes)?
What is the fuction (linear) to use for this extrapolation?
I'm trying to solve a simple convection in FEMAP
How can I choose the properties of the air in FEMAP,
namely its temperature, h, and eventually speed? Am I supposed to defined some sort of infinite reference point with the air properties?
I'm also attaching the model as it is now, for those...
