Hello
In this standard, safety-related parts of control systems, what does the 'd' of MTTFd mean? I know it means "dangerous (failure)", but it also talks about a safety system failing to operate.
If a safety system failing to operate places the machine it is protecting into a default safe...
My company is looking at purchasing this software. We currently have seats of Inventor where we can create pipes, adaptive or otherwise, with 3D sketches. Could anyone offer some experience-driven opinion please on what there is to gain from upgrading: for example, what can you do with Routed...
Apologies for such a non-specific post, but I am essentially trying to assess the feasibility of something I know next-to-nothing about.
I am, in essence, after a pump to move liquid pentane in a (very small) closed loop system:-
Metric: 194m head, 3.6m3/hr (or 1 litre per second)
Imperial...
I hope I've submitted this in the right place - seems the most relevant...
I have a simple sounding question - is there a preferred system for numbering drawings and/or parts?
I have in the past used a system where the part number gave information about what the part itself was, another system...
Does anyone know where I might find a worked example using this specific EOS? I have made a spreadsheet for using it to calculate thermodynamic data (I am not a thermo guy, by the way) but the answers it gives me don't appear to make sense. I'm only really hunting for a mistake in my...
I have had cause to look at a couple of stripped down scroll compressors (from two different manufacturers), and in both instances it was noticed that at the bottom of the labyrinth profiles, on both the stationary and moving part, there are sharp corners. By sharp, I mean almost non-existent...
I have an application where it has been determined that 2618 aluminum alloy is the prime candidate material for high fatigue life at elevated temperature.
This decision was largely based upon fatigue data (at elevated temperature) for 2618 with a T6 temper (wrought stock material, not bespoke...
Hi
I have some experience in applying 3-2-1 supports for 3D FEA models to remove rigid body motion in analyses, and am trying to replicate the idea for a 2D axisymmetric model.
I have geometry in the +x, +y quadrant of the XY plane. Within the model I have constrained 2 points along a line...
Hello.
I have seen a number of stress-strain curves for grey cast iron indicating permanent deformation after application and removal of a load. In all of the instances I have seen, however, the first load application gives rise to a stress that is some significant proportion, say 40% or more...
Hello
In the help system for Ansys Workbench 11, it says that you can now attach surfaces from Inventor models - I'm fairly sure that at release 10 this couldn't be done at all.
The above statement may well be true, but I cannot for the life of me figure out how to generate a 2D surface model...
I have a number of questions regarding stress analysis of irregular geometry in grey iron castings.
(1) How can I evaluate the theoretical stress concentration factor (using FEA techniques in my case) for irregular geometry? I have read that for, say, a simple bar in tension with a notch...
