Hello,
I have a small design task for an R&D project and I'm trying to find an off-the-shelf solution for some flanges. We are building a small pressure vessel with a roughly 2.5" ID. It will operate between ATM and 150 psig, ambient temperature......should be easy.
There are several spool...
Hello,
I am running a static analysis on an assembly that has some bolted joints. In addition to the stresses in the parts I am interested in the forces in the preloaded bolts to make sure they are not overloaded. All the bolts have a fairly high safety factor and I am not overly concerned...
Hello,
I am a Mechanical Engineer and an FEA beginner. I consider myself to be familiar with Solidworks but not Simulation nor FEA in general. Although I have a B.S. degree the coursework on FEA was not much more than "press these buttons, make pretty graphs, there's your answer".
I think its...
Hello All,
I am looking to purchase a CNC Mill for our R&D facility. We would like at least a 4 axis Mill with something around a 12" working area. We machine all sorts of materials from stainless to plastics. The machine is not planned to be used for production, mostly one-off's.
We use...
I'm having a problem properly calling out threaded holes in a drawing.
I have two parts, they bolt together. When I use Hole Series to create the clearance hole and the threaded hole at once I am unable to properly call out the thread in the drawing. In the drawing, using the Hole Callout...
Hello,
I am using Simulation for a transient thermal analysis for the first time.
To start I am simply modeling a solid copper rod with a heat load attached at the end. The heat load (watts) varies as a function of temperature. The heat load is actually a cooling curve taken from one of our...
Large P&ID's usually get sent to our designers but I have a lot of small projects that simply get drawn out on sheets of paper or made up using some arbitrary program like MSpaint. I am trying to find a relatively inexpensive program to make up P&ID's. I'd like it to be stand-alone (not an...
Hi,
I have a budget of $5-5.5K for a new computer (including the monitor) that will be running Autocad. It has to come from Dell and it has to run Windows (Vista or XP?). Our current PC reads like this...

Hi,
I want to polish up some copper heat shields we will be using in a test bed. What is the best way to do this? The techs I talked to have used Semi-chrome (a household polish) followed by Acetone and not had outgassing problems. I was hoping someone might have a better idea or a confirmation...
Hello,
I have a Cryo Test Bed we use that consists of a ~4 cuft dome evacuated with a small turbo and cooled with an ancient cold-head. There is no LN2 cooling or any other cryogens introduced into the system. (for cooling or otherwise) .
We have a pressure relief valve on the chamber but it...
