Need help defining joints to simulate design function

[leandro.scovino]

I'm designing an electric gate to my home, and I'm having some issues. Decided to simulate the mechanics to proof of design.

Simplified everything I could, wheel hubs and hinges, but simply can't make it work correctly in Fusion 360. The door is fully articulated, and needs to make the curve to close.

Thanks in advance.

Your attached F3D file is empty.  Please try again.  Maybe you should try and download and open your file before posting to validate if it is valid.

Hi John, thank you for the heads up.

Now it's going to work.

I ripped up your assembly to create one that will illustrate the ONLY way you are going to get the door wheel to follow around a curved track.  Contact Sets will NOT work in your model.  You have to create Tangent Relationships and these can probably only be on either the top or bottom of your door.  I would suggest the side I used because of the track and wheel simplicity.  Constrain the other components to just follow along.  The Screencast will explain my method and I attached my "ripped" up assembly to let you play with.  I hope this will give you an idea of how the tangent relationship will be the only way to solve your issue.

Hi John, I'm very grateful for your help!

I was able to replicate your design but, when I add another door, everything brakes.

Well, I guess I'll have to think another way to try this. The main problem here is to define a good curve radius according to door width. If I use a small radius, the system doesn't work well.

Based on some sketches and calculations, I believe a curve radius of 115% of the door width is good, but I'd like to see this working. I hate to go empirical hahaha.

Thanks again, John.
