Hi everyone,
I have a question about bushing joint in ANSYS. I'm using ANSYS 14 but will have access to ANSYS 15 soon.
I'd like to effectively create a spherical joint which has some stiffness and damping in the rotational degrees of freedom (DOF's). I think I can do this by using a bushing...
Thanks for your reply,
In that case I'll avoid doing either of those things as it's a new drawing. I fully agree with you, with the new CAD software it's possible to do all sorts of wierd and (sometimes not so) wonderful things.
Out of interest which is the best standard to refer to for...
Hi everyone,
I have two questions about detail views:
1. Is it good/accepted practice to section a detail view on a drawing?
2. Is it good/accepted practice to create a detail view within a detail view on a drawing, nesting the detail views?
Many thanks,
Tom
Hi racookpe,
I was planning to use the small case that came with the light and battery pack that I bought. It is just a fabric thing with a velcro strap. It's in no way waterproof or IP67 or anything like that, but it's adequate for protecting from a bit of rain. It goes in my saddle bag so it...
Hi Everyone,
I'm planning to build a 7.4V battery pack to power my bike light. My current battery has died as it was left for a long time. All cell voltages are now well below 2.0V so I've disposed of it.
My pack will contain 4 x 18650 CGR18650CG cells in 2S2P configuration, as shown here. I...
Hi everyone,
I'm having a bit of trouble finding a graph or table showing the change of bulk modulus of water with pressure. I have some limited data from the Roymech website, which gives the change of bulk modulus with pressure up to 200bar, but I need to extend the data further than this, say...
Hi Morten,
Thanks for your quick reply.
Ok in that case I'd be simplifying things too far if I didn't take into account the dependence on mass flowrate in the equations.
I'm designing the system from scratch so I can accommodate whatever flowrate I want, within practical limits obviously...
Hi Everyone,
I would like to set up a thermodynamic/heat transfer model of the following system. The system is a closed system which cools an electronic device which is attached to a heat sink, the water circulates through tubes between the heat sink and a cold plate, rejecting heat to the cold...
Hi Compositepro,
Thanks for reply, the link you gave has the information I was after. Page 16 of the document in the link below has the table I was looking for and also mentions that all threads are Class 2A or 2B.

Thanks again for your help!

Hi Everyone,
Could someone please explain to me the thread dimensions used on medium pressure autoclave connections (up to 20,000psi)?
As I understand it, an "Autoclave" connection essentially consists of a UNF male thread on a cone ended tube, which is screwed into a matching female UNF...
Excellent, thank you all for your help on this.
Yes I was referring to a change before the melting point is reached and melting of the metal occurs.
It is this change in crystal structure and grain size that I need to look into further for the metal in question. I will also look into relieving...
Thank you both for your prompt replies.
The component being heated is not constrained and is free to expand and is free of residual stresses.
Further to my original question, is there a temperature limit for any given material after which it will not return to it's original dimension once...
Hi Everyone,
I have a general question here which may or may not be a stupid one but I'll ask it anyway.
If a material, let's say mild steel for example, is heated up it will expand. When it cools it will contract again. Does a stress-strain curve as seen in typical tensile tests apply to...
Thanks Jerry and Toost,
Your replies have been very helpful!
Yeah it looks like I'll have to carry on moving objects in a part to layers by making it the displayed part then. (at least until our company upgrades to a newer version that is.)
Many thanks,
Tom
Hi,
Can anyone help me?
I'm fairly new to NX, working on NX4. I am working in context on an assembly (we'll call it "assm"). I've created a part (we'll call it "part1") within the assembly and made it the work part, with layer 1 as the work layer. "assm" is still the displayed part.
When I...
