"Nice example of failure analysis using SnS.
I like SnS for the same reasons.

Hello AllI finally got around to playing with V-Ray last night. I was wondering what material to put on one of the objects when I wondered if the VRML file exported for 3D printing would work.It…Continue

SnS helps reinstatement of guillotine
My position as popular contributor appears to be slipping, I'd better give an example of how SnS helps solve real world problems...We have a veneer cutting guillotine that is down. Not only are both arms (holding the blade assembly) broken (and inneffectively repaired) but also the joint/coupling that swings the blade. Note the original flywheel/motor drive has been replaced with hydraulics.My job is to get it back up and running asap. Repeated attempts at welded repairs have failed and the RHS…See More
Vadim Shapiro commented on Ian Boyd's blog post 'Thank You!'
"Ian, congratulations on the well deserved promotion, and best wishes for 2012! "
Ian Boyd posted a blog post
Thank You!
To Vadim, Michael, the SNS team, a big thank you and all the best for the festive season!Extensive component testing (and development as a result of that) has seen me promoted to the position of National Product Manager, with my own R&D team, supplying products to five companies. And back to engineering school.2012 is going to be busier than ever. SnS will once again be playing a critical role.RegardsIanSee More
Ian Boyd replied to Rendy Himawan's discussion 'Office Chair Analysis'
"Hi Rendy
The prototype looking good!
8mm steel for back - no problem - if you run into difficulty with BIFMA look at moving to something like SAE1010 alloy (used by the auto industry for the same reason).
The problem with people who approve things…"

"Hi Rendy
(Sorry for taking so long to reply... a bit hectic here). It's a good thing to be testing with SnS now but there is still some road to travel. I am making the assumption you are serious about going into production.
I have…"

Ian Boyd replied to Ian Boyd's discussion 'Dauphin - Rendering SnS Results with V-Ray'
"Adding to my own post...
I was being silly - there was no need to export/import the VRML file... just bake with textures.
Nevertheless, it niggled me that I had to manually tweak the texture map and fake in a shadow below the FEA object - it…"
Ian Boyd replied to Rendy Himawan's discussion 'Office Chair Analysis'
"Hi Rendy
For the US standard on chairs you need to look up Ansi-BIFMA, X5.1 (backrest overload test, see attached). This is also pretty much a global standard.
The BIFMA load criteria (406mm from seat, etc) will probably not match…"

Dauphin - Rendering SnS Results with V-Ray
Hello AllI finally got around to playing with V-Ray last night. I was wondering what material to put on one of the objects when I wondered if the VRML file exported for 3D printing would work.It came in perfectly, the texture mapping 100% OK. The material is of course Rhino based (not V-Ray) and I had to tone down the brightness of the *wrl.png texture in Photoshop (50% but in retrospect, more would have been better).The next step will be to see if the material can be converted to V-Ray.I have…See More
Ian Boyd replied to Liam Woolley's discussion 'Accuracy.....'
"Hi Liam
To illustrate my point in last response regarding assembly stresses. Designers cannot work in isolation (as they so often do) from the realities of a product's 'life cycle'.
SNS, and I suppose any analytical…"
Ian Boyd replied to Liam Woolley's discussion 'Accuracy.....'
"Hi Liam
I read your discussion while testing a cross rail for a chair, which is not much more than a simple cantilever beam with an end load.
I'm using a steel with a tensile (yield) strength of 420MPA. End load 2520N. SNS reports Danger…"

Dauphin Human Design Group - 3D printing
We have just received our first SNS 3D prints... In our quest for ever-improved products, this will take our discussions with toolmakers, injection moulders, materials specialists and so forth to a new level. To wit - this is a little (chair) mechanism housing we have been considering changing from cast zinc to glass reinforced polypropylene. There has been some further thought on that, however, and we are now considering recycled carbon fibre reinforcement. Q: Why?A: Rising metal prices (steel…See More

Dauphin - Frame Redesign with SnS
I have been using SnS for almost a year now (chair manufacturer). The affect on product reliability has been profound though I must qualify that by saying it has meant going back to the textbooks (most notably Shigleys) but the results have been rewarding.The following is a little case study of a chair frame (German design) that went from being a fragile “breaker” to a zero return “battle tank” after some careful redesign. Bear in mind also that we are not permitted to change the aesthetics of…See More

One of the key learnings from Shigleys is understanding the different stress analysis models. For instance, what differentiates Maximum Shear Stress (MSS) theory from Von Mises? Why use Coloumb-Mohr? There are some things I still…"
