compression spring

[Anonymous]

Hi !

   I want to design a variable pitch compression spring for automotive shock absorber assebmbly model.

   For this design , I need to consider variable pitch, variable angular pitch & varible coil diameter.

   In Fusion 360, its a limit to design to this type of complex compression spring.

   I want to know, is their any generic method to design such a complex helical coil in Fusion 360.

Hello,

there is possible to use Coil which allows you specify 'Angle' parameter . This angle parameter defines angle for  Helical spring.

model parameters

Hi,

Yes there is a option in Helix coil feature to define angle parameter.
But, can I design a spring with different pitch, combination of angular
& normal mean dia.

Not directly, but i might have a workaround for you.

If you start with the regular helix feature, set the profile to be to the inside. set your desired pitch and angle:

Create a sketch on any plane. Select the edge running along the outside of the helix body, and choose Sketch > Include 3D Geometry:

Now hide the helix body, and add a 'Plane along Path' at the start and end, and anywhere in between where you want to control the diameter:

Sketch you desired diameters and then loft the profiles using the 3D sketch as the centreline:

I hope that was sort of what you're looking for, maybe it helps!

Cheers,

Niels

Yes I know this feature to creat helix, but i wanted something different.

Was there ever an answer to this?  I have the same question.  If you have the solution, please let me know.  If I were using another CAD program with a helical feature, I would project a new circle at the end of the coil and make the helical path around the same axis, but at a diferent height and pitch.

I replied with my solution on Eriks post.  Its the lightest easiest way to get the result you need.  Check that out and let me know if you need follow up.  The other way is a spline through points driven by a table or algorithm.  Way more complicated approach but scalable in ways copy/paste/move aren't.
