Thank you for this. I have looked at quite a few articles as well as the ANSYS learning hub training however, all the examples appear to use a gap or flexible gasket between the two flanges so there is no flange to flange interaction or load sharing and that's the piece I'm struggling to...
Unfortunately I don't have a model and I'm not the analyst on program but this is a debate we've been having so I was trying to figure out how other people would model this. Currently they're only using a beam element with no Preload but it's causing us to chase stress areas and I think it's due...
Part A is tapped with a helicoil installed, part B is a thru hole. The fastener would be installed and torqued according to our internal torque spec. By applying preload does this change the behavior of the joint or just the beam element? For example would the two flanges still be allowed to...
Here is a quick sketch of a joint concept and you could assume a load applied at the middle of the plate. The Socket head cap screw is replaced with a beam element tied to the head contact area and the helicoil area. You can assume the Part A is restrained on the bottom surface as fixed support...
I'm going to apologize up front as I am not an ANSYS or an analysis expert by any means but there is some churn within our department about handling joints and I'm hoping someone can educate me.
We have a bolted joint with a fastener, washer, and helicoil. The fastener is a #6 (.138) and the...
Drawoh,
I understand but what I'm struggling with is how do communicate this. The epoxy vendor gave me a 2500 grit finish but that's not something I can just push on the print since 2500 grit isn't a surface roughness (I don't think) so I'm struggling with how to translate what the epoxy vendor...
Does anyone have any recommendations on how to communicate surface roughness for bonding? Normally I'd just say something like "abrade surface using X grit" however, in this instance I cannot since it's optics I would rather just communicate a target minimum roughness. I have talked to the epoxy...
I can't find it in Y14.100 so I thought I'd ask here... Is it acceptable to change the scale on a projected or section view as long as you put the scale below the view name? I've never done this but a co-worker is asking me if he can do it on a section view (not a true projection in this...
First I will appologize I'm far more a mechanical design engineer than a stress analysist at this point in my career so I'm probably going to phrase stuff wrong. I'm also not completing the analysis but am helping on the design side.
When a model analysis is competed you end up with a list of...
Thank you. I do have that document but these are vendor installed so the process isn't super clear to us.
I do know the boss diameter wasn't done per the spec but I don't know if this affects static strength, creep, or both (assuming both). One question I'm having a hard time answering is "what...
Heat them up with a soldering iron and slowly press them in (melted plastic flows into grooves and such). I'll see if I can find a link but they are made by Dodge (Stanley) and are called UltraCert II... The hole is modeled per the spec and printed in place (potential point of problem due to...
Un-reinforced being applied with MJF currently
Yes 3D printed using MJF process.
Long term thinking potentially bolt/nut with a washer but the question is how much bearing area is required to not cold flow over the life of the product (hermetic seal). Trying to find a way to save the current...
I am hoping someone might have some knowledge that can help me out. I am a Mechanical Design engineer tasked with solving a problem with an existing design. We have a set of grown Nylon 12PA parts that get bolted together with an O-ring between them. We have heatsert's in the base with a #6...
Thank you! I got it and I think I came up with a sudo real world example to help communicate this topic (where using the pierce surface would not work for the assembly)
I have been a design engineer for ~10 years now using GD&T almost daily. I have recently started a new position with a younger team and have noticed a lot of DRF changes to make the pierce surface the primary datum for holes. This is obviously causing a lot of useless datums to be generated as...
