Drag Component & Detect Collision

I am trying to detect the collision of two rotating parts defined with a gear constraint but can't get it to work. This was just a test case I tried. It works for other types of constraints but not gear constraints. What I'd like to do is get the rotation to stop when a collision occurs. Any ideas?

I believe that the Gear Relation is more of an animation setting than a physical relationship.

 

In this example, it looks like you could simply apply 2 separate relationships to tie the rotation(s) and set them equal in via variable table...    either floating mates, planar align, parallel, angle...

Hi @David_McMahon

 

 

 

what if You use the Physical Motion ?

 

This will detect real physical relations between any surfaces during the simulation

 

PS.: this is an option in Assembly - Drag Components function

Seems like it should work to me.

It highlights the faces when you use Simulate Motor with detect collisions option.

I tried physical motion but I can't get it to work. Seems like a limitation with the gear constraint.

Hi @David_McMahon

 

 

You should supress the gear relation first

Give it a try

I also noticed that if you set the axis and then enter an angle like 1deg. then just hold down the return key

it will highlight the faces when they collide.

It will  not stop on collision for some reason though.

But this also makes me think it should work with dragging and maybe you should call it in.

Very intersting observation that the collision works if the rotation is bumped in small increments. I have opened up a ticket with GTAC.

 

Thanks to everyone for their help.
