Not a bad thought and something I'll probably try as well.
The downsides I can see are the 0.55mm sheet being very thin and I really need the face opposite the ribs to be smooth. So would need post-weld linishing and a touch up with paint. But still it might be feasible and still automated for...
A bit more information...The actual, part, is slightly curved. The aim was to use the bottom edge of the rib as a laser cut or custom guillotined profile to provide the support without having to stamp or rollform the support. The welds along this length would hold the 0.55mm sheet in place...
I think in this application (which I haven't fully explained, company IP, etc) friction welding wouldn't work. I need the workpieces to remain very well aligned during the operation.
Plus the final part is big-ish - car body panel size...
Will probably see about running some sample parts on a...
Hey MJ,
I agree that the weld strenght would be vlow, but think that can be compensated for by a number of welds along the rib length. What I've shown in the image is a small section of a larger part.
Had another thought that similar to stud welding a V-shaped projection could be on the rib...
Hi,
I have a question regarding a custom spot welding application: Is it possible to spot weld through the thin edge of a sheet metal (~3mm) rib standing perpindicular to a mating flat sheet (~0.5mm)? (See attached pic)
And the sheets may be pre-galvanised!
My experience with RSW is...
Thx Jiligeo,
I think that might work.
The example is on the same model so they will have the same connections - at least in workbench. But it looks like you can read/write an IST file using this command. So I'll try that or write another command script to activate a connection in the second...
Hi,
I'm sure the answer for this lies in a clever APDL script, thanks to the repackaged limitations of Workbench v12.1, but...
...in brief I would like to pre-stress a model with applied loads then in a second model activate a contact to mimick an adhesive between two parts that is being held...
Hi,
Looking for some expert advice on whether to use Victaulic's or compression fittings. It's for an enclosed heat exchanger skid with a max 400kPa pressure rating running 2" & 1" PE100 PN10 pipework between the system components.
Aim is to implement the most robust (ie. least maintenance)...
Hi,
I have a product which incorporates a laminated piece of glass to a polystyrene substrate. I have read some background research about the potential for water accumulation in polystyrene due to thermal cycling and water vapour transfer. I am interested in the affect of this combined with the...
I'm in the mood to share some info, so here goes...
If, like me you're not keen on using Ansys Classic, here is a script to export/capture node information from a surface in Workbench...
Overall process is to: a) Create a named selection set (eg Face) of the surface of interest b) ensure it is...
Hey SDE,
Thanks for the tip. Had already started down that path as one of my colleagues showed me a demo that he had using MPC184's. I've now spent the day testing with the MPC184 element which appears to be quite handy...Here's the script and some basic instructions for implementing it in...
Hi,
Any help on this much appreciated...
I am trying to setup a modal analysis for a scissor lift mechanism. Putting it simply: it is a 4 bar linkage (including ground) with a fifth bar connecting across two joints.
Therefore whilst the linkages are connected by pin joints, the mechanism as a...
Hi,
I was wondering what building classification (ASCE 7-05 Table 1-1) should be used for wind turbines, and other renewable power plants?
I would assume cat III, but was wondering if a renewable power plant might fall under cat II if it is providing surplus energy supply to the base load -...
Thx LTC and Wancho...good links.
Abchance had some really good info and that pre-cast pin foundation is very interesting.
I passed some interlocked road barriers in the street the other day. Another potential solution that I am considering...

thx civilperson...I found a few more potential solutions for supporting 'very' small structures...
In addition to the small pre-cast pad idea I was also pursuing screw piles / auger anchors? Possibly to be used in conjuction with a precast pad to increase load capacity. But again have no...
To explain further...
By lightly loaded I meant something similar to a pole mounted street sign, only with a larger swept area and therefore higher wind loads.
Preliminary design for such an above ground pad estimates a requirement of a square pre-cast pad ~700x700mm and ~150mm thick. Giving...
Hi,
I am trying to find technical design information on the use of pre-cast, ie above ground, concrete pads to support small lightly loaded structures. Something similar to temporary road barriers.
Of my concerns with employing such a structural foundation is:
1) soil settlement
2) soil...
I came across an interesting piece of software the other day called Ecotect by Square One (http://squ1.com/).
It appears, on preliminary review, to provide some good tools to predict sun shadowing and annual solar energy on a surface, which is of particular interest for solar power plant...
Hi,
Has anyone seen or implemented non-parametric bead optimisation in Ansys WB or classic?
I've seen/read about the functionality offered by Altair's Optistruct, Tosca, etc, but was interested in finding out a way of performing similar analysis in Ansys. Particularly as this functionality...
Hi,
Supposedly in Ansys 12 there's going to be new functionality to more easily allow the export of deformed geometry. But in the mean time here's a method of exporting STL based data from Workbench.
I can't claim any credit for the original STL export script (ie. the difficult bit), that was...
