Creating a spring feature shape..
(OP)
Hi Guys,
I have a single component with a spring feature in it I am working on that I can model without a problem in the compressed position. The component consists of basically a rectangular steel bar that is bent over in the middle 180 degrees so the two sides are then parallel, that is the compressed position. I need one side of the part to have a curve in it (the spring feature - the part is pushed into a pocket that compresses the single arm). How can I add this curve to the arm so that it goes back to the same compressed position? - I need to set the height of the arm with the curve in accurately - easy in the compressed position but the part needs to be manufactured in uncompressed position and then heat treated..
Any help received is gratefully appreciated!
cheers,
James

To an Engineer, the glass is twice as big as it needs to be.
RE: Creating a spring feature shape..
of course! (sorry). Here is a small animation (.mp4 file). The solid body shows the spring in the desired compressed position. The sketch lines show where I would like the uncompressed position to be (approximately). This is a hack but I would like to know how to do it properly so that the top of the spring 'leg' will be in the known compressed position when compressed. How can I do this and how should I be thinking about it with regards to Nx functionality..
many thanks,
James
- using Nx6

Also, this particular model will only give a reasonable facsimile of the part when deformed. You would have to run FEA to see how it actually deforms.

Each one gave me something to think about and I have now solved my problem..

RE: Creating a spring feature shape..
I have hooked this challenge onto this eMail thread being of a common Theme, springs.
in my case i have a deformable spring
this spring is preloading a spool
my objective is to create a screen animation with NX7.5.3.3 of the spool transitioning between two points and that the spring deforms accordingly during this move
any ideas where to start, ? - what NX functionality is best placed to tackle this
