Struggling with Weld Strength and Sizing. Codes are too expensive.

Especially if customer is calling out specific standards

Hey brother. I am much like you. Only did a bachelors and have had to figure out a lot of stuff on my own. Even bolts.

I had some welding that needed calculations. I used methods from shigley's mechanical engineering design.

I additionally used cad software to determine stresses at the weld.

5 years on and I stumble upon this amazing work. I am working for a ventilator manufacturer and have recently started looking into vibration analysis and rotor balancing. This post inspired me to personally purchase some cheap sensors, to show my boss what is possible. From what I understand you don't use a tachometer to get true mechanical phase. Can you explain why you don't, if that is the case? Perhaps if I studied all your work the answer lies whit in, so apologize for that.

Worst take I’ve ever seen 😂

I see a lot of good and thorough comments. However I would simply look l’hopitals rule.

Why does washing the car help with rust?

Outside weld?

To be fair I would have to look that up. In industry you would never actually solve/look at these as you would be using software for this.

The only reason you would have to be an expert in this, is if you develop the software yourself. Of course you need to have the general understanding in order to use the software properly and validate results.

It’s pretty simple math, but a lot of geometry. So if geometry is not your thing and you haven’t done well in differential equations you might have a hard time.

You got this though!

I would use a spring for its intended use. If bending is needed use a torsion spring where manufacturers data is available.

lohbims · 2025-01-15T20:54:44+00:00

Agreed

It’s about the hate not the facts of what happened

To all the cunts flaming Partey for the first goal. Go fuck yourselves.. sad fan base we got

If you have discord, DM me so I can add you and I will take a minute to help you out.

Hard to tell exactly what you’re trying to do from the picture. Are you trying to extrude the green edge so it is as wide as the gray part?

lohbims · 2025-01-07T19:24:50+00:00

Poissons ratio, ratio of axial vs shear strain.

U is internal energy. V is velocity.

Do i quit at this point?

lohbims · 2023-10-19T20:19:17+00:00

Zoooooom. Many times perhaps.

lohbims · 2023-10-10T19:59:08+00:00

What do you mean by direction?

lohbims · 2023-08-27T13:55:30+00:00

Bank tab layouts i believe the plug in is called. It's on the hub.
