Got asked by a student today if I would consider myself a skilled CAD user. Not really related to the subject at hand and they've never seen any of my CAD work... My answer was that yes, I would consider myself a skilled CAD user. But it got me thinking. What makes one a "skilled" or "expert"...
So, I scanned this section for a thread that sort of answers my question but once I got down to 2009 I figured I'd better ask...
A small company is looking to start up locally and need to look into what CAD software to use. I may be one of those who will be active in this company, or I may not...
this has sort of been covered in the "to switch or not to switch" thread, at least partially.
I'm currently working as a designer for a large company and have gotten pretty good at designing plastic components. I've been there for a while and it used to be a stable place except now HQ has...
I'm trying to measure the change in efficiency for a duct system. As it is, the fan is blowing air straight into a wall and the air then travels down a channel towards a series of outlets (imagine a fan situated in a short circular tube connected perpendicularly to a flat and wide rectangular...
Apparently, with the last re-organization of our R&D department I was considered to be sort of our "expert" on FE analysis and mechanical strength calculations.
Yes, given the limited education I have regarding FEA, this is worrying.
The software we use for FE is Catia V5 and we currently have...
I'm doing a series of FE analysis on a plastic shelf with steel reinforcement bars and just today noticed an annoying error I made: I have been using a "rigid connection" between the reinforcement bars and the plastic. As I understand it, the rigid connection results in an infinitely thin...
I've been given the task of trying to fit an existing lamp into an existing component. I have been told to just make it fit, meaning that I may modify component carriers which were previously sacred. Now that it seems I have found a solution for the bulb (and socket) to fit there is the problem...
I'm looking at how to improve a component which is in direct contact with a heater. The objective is to improve heat transfer between the heater and this component. I have a pretty good idea of what I want to do for my analysis, but I'm not sure it's doable within GPS. I want to apply a...
For one of our products we currently employ a hexagonal tube for transporting drain-water. Short description:
At the top end, the drain-water passes through a nipple with circular inlet and hexagonal outlet into a plastic hexagonal tube. At the bottom end of the tube a nipple with hexagonal...
I'm looking at a particular component which will quite often break during testing. I have this component in two versions, one made from Zn 5, one made from EN AC-46100. Trying to get an understanding of why they break (or why one would break and not the other), I am now wondering if the...
I am testing a new version of an old handle for refrigerators. The handle is basically an aluminium pole with two brackets at each end holding it to the door. Changes have been made to both the handle and the brackets, so I try to test them separately, sort of. I've tested the new handle with...
So, having a car with combined rotor/hub (an '85 fiero), I'm looking to upgrade the brakes and might have to manufacture new hubs or at least modify the existing rotor/hub. What do I need to know in order to avoid making huge (dangerous) mistakes? How do I approximate the forces on the hub?
I'm trying to understand what happens when the air is flowing inside a refrigerator but without knowing the basics, that is kind of hard. All I can do is measure the temperatures and guess what is happening. That needs to change.
I need links to sites which can help me understand what happens...
I have the following basic case:
|===a===b->>
at a I have a force F. at b I have the same force in the opposite direction and a moment around the x axis
Now, using catia generative part structural analysis, how would you model this? Particularly, how would you model the force at point a?
I am...
having acquired a CFD code called elmer I am a bit curious. The reason I downloaded it this time (I have tried using it before but not really seriously) is that I was curious as to whether or not it could help us solve a few air-flow problems we have (we are not really allowed to get help from...
I am experiencing some difficulties while setting up our measuring system. I am using ScadaPro software and Datascan modules. It all seems to work well up until the point where I configure the calculator channels. I made sure I tested the system with every change I made, and it all worked fine...
For some time now I have been testing a new door stopper design for our products (refrigerators) and I figured I would see if an FE analysis would have helped us do this faster. However, I have one problem: the impact force is not known and neither is the impact deformation of the door stopper...
For some reason I have been assigned the task of installing and setting up SCADA Pro on a new server. I suppose it's because I am the only one who has taken an interest in learning more about the equipment we use while everyone else seems satisfied with just being able to use it as it is. While...
Being a "beginner" in FEA (I did receive some education in Pro/Mechanica and have been doing small work with Catia's GPS, but I have not been anywhere near a professional FEA code) I have a few questions.
The first question concerns Catia and the restraints (correct term?) available. I need to...
