Making a component lock in place

Hi

I'm trying to make a simple mechanical locking mechanism for a project, and I want to simulate this in fusion.

Here are the components, C1 and C2Here are the components, C1 and C2

I want to lock C1 into C2. (C2 is a cross-section of a larger piece, but I sliced it to see the locking mechanism).

I activated contact sets so that all components collided, so I could test if my model worked, although, I want to anchor C2 in place.Rotation.PNG

 

This is a rather crude diagram of what happens from a top-down view. The blue arrows indicate the motion of C1, and the red lines show the limits of the joint, so that it cannot rotate more than it should. The blacked out area is where C1 aligns to be removed from C2. 

To test the limits of the joint, I went to rotate C1 in the wrong way, expecting C2 to stay in place, although what actually happened is C1 pushed C2 along with it.

What I want to happen is for C2 to not move at all, but still have collision with C1. I tried converting C2 into a body to see if that helped, but then the components didn't collide.

Is there a way to have C1 as a component, have collision with other components, but be anchored down in place?

 

I apologise if my description isn't fantastic, I'll be happy to explain again if needed.

A couple things:

 

  • To "anchor" a component in an assembly, you can right-click on the Component in the browser and choose "Ground"
  • It's better to create the Revolute joint that you need between those two components and just set Joint Limits on that newly created joint, to simulate the kind of movement that you want. This is better than using Contact Sets, which are really computationally intensive and, in your case, are doing the same thing.
