Hello all,
I'm running Workbench 12.1 and recently it started having issues grabbing the Mech HPC license. Once workbench is started it will be able to grab a license for a few solves, and then it will fail to grab the license until I restart Workbench. The only way to solve the model at that...
The error message could one of many things.
-Could be that the body types you have selected for import are not in the model
- Could be that you don't know to select what types of bodies you want to import (In the workbench window you show, click on the GEOMETRY box, make sure you have...
It depends on what version of WB you're using. Pre-WB12 you need to create the material cards OR import them in the form of a .CDB file from ANSYS classic. WB12 and up you edit the Engineering Data and input your properties for the various materials after dragging over the property in question...
Hello all,
I've had Workbench 12.1 thrust upon me and am trying to figure out how to apply a moment to a 2D axisymmetric model. There's "Moment" listed under loads but it doesn't seem to work for me.
I've modeled a splined shaft as a 2D axisymmetric model (Y being the axis of revolution, of...
Hello everyone,
I'm trying to design a crown on an external spline in an attmept to distribute the load over the length on the spline. Initial FEA shows the bulk of the load is taken up at the start of the spline so I'm trying to redistribute the load for lower stresses and more life.
Is a...
All, I'm trying to define an internal spline for a mating shaft to an already defined external spline. When I go the Machinery's Handbook 26, the major dia of the internal and external spline (Dri and Do respectively) are defined exactly the same way as N+1/P. Since they can't be exactly the...
I believe you would need to know the deceleration time of the original bench test to make any sort of comparison; knowing the speed at which the vessel hits the bench divided by the duration of the impact will give you the acceleration or g's. Wood allows a longer contact and decelration...
Try eliptical nuts, they're deformed out of round so that when you use them there's an extra load that keeps them tight. However, unless you use a mechanical fastener some vibrations will always loosen the nut. In the good old days they used lockwire to hold nuts in place, it fell out of favor...
There are several contract houses in Massachutesetts, you could try Belcan out in Lynn. The rate would need to be negotiated but plan on ~$80/hr. There's probably also CDI.
Hello, I've never designed an inlet diffuser BUT I would imagine the flt pt is cruise, the aero folks design the gaspath (and hence the shape of the inlet diffuser) at the point they want max efficiency. For commercial applications like the JT9D you would want max eff. at the flt pt you sit at...
OK, it seems a large number of people forgot what SOMARP was looking for: the CG. Suspension et al is irrelevant to the problem b/c he measured each wheel independently. The supension forces would come into play if you had the total weight and CG and wanted to find the load at the tires...
MintJulep is right, it's just bad pratice to use spring lock washers, if you can't use a locking compound use eliptical or deformed nuts, sometimes call self locking nuts, with a bolt. And tighten the nut, not the bolt.
You're forgetting moment balanace equations for the two car planes. Suspension doesn't matter.
(LR+RR)*X1 = (LF+RF)*X2
X1+X2 = forward to rear wheel dim
X1 = dist from rear to CG
X2 = dist from front to CG
Two eqns, two unknowns: pretty easy
Then do again for side to side.
Has anyone succesfully added their own material files to the .XML library Workbench uses? Could I get a dummy copy (you can remove all the data, just leave placeholders please)? I can't get the format correct, the original files only have temperature dependent fatigue properties and I want to...
Most materials do not have a "creep limit", creep is a function of temperature, stress, and time not just stress. Creep occurs only when the load is applied at a temp above 1/2 of the melt temp of the material, below that temp another phenomenom is at work (fatigue typically). I have no...
Hello all, I'm looking for info on curvic couplings, their shape, standard sizes, how they're cut, load calcs, etc. I've contacted some machining suppliers, would like to get a head start. Any and all info would be appreciated.
No, one would think with all the RPG's the US destroys and all the war trophies people have been bringing home since Viet Nam that there would be something.
I've included this also in the Ordinance Forum but since there were only three posts in it, this forum is probably a better experience/knowledge base.
I'm looking for schematics of the RPG-7 (or other RPG munition) rocket. Some online sites provide a crude artists rendering, but nothing...
I'm looking for a schematic of the RPG-7 munition, in particular the circuit path through the ogive to the detonator. I've looked online and found crude artists rendering, but nothing giving dimensions and what not. Additionally, I'm looking for whether the forward (towards the target) side of...
