Problems getting Dynamic Simulation to work

[Anonymous]

Likely I'm doing something wrong, but I'm trying to make an indexer work

In the top, there's a groove that springs are supposed to push against to make it align
in the bottom are 2 spring loaded plungers from VLier

I'm not getting the things to work the way I think they are, I need to find o ut how much toque it takes to get this to turn.

I'd post the files, but the zip is 23 MB, and so i'll need to upload it to an FTP

Hi Donovan,

I've emailed you our FTP info. We'll take a closer look once we get the datast.

Thanks!

[Edit: Hi Donovan,

Thank you for providing your dataset. I’ve pulled the zip file off our server.

We’ll look into this and share our findings soon.

Thanks, -Hugh]

Any word on this?

Hi Donovan,

I apologize for the delay.

What I'm finding is that in the Simulation you provided, the plungers are not contacting the indexer surface(s). You can see what I'm referring to if you re-run the simulation.

If we unsuppress Revolution:1 Joint (the one with the imposed motion) and run the simulation, both plungers are penetrating the Top part.

Once the Simulation is updated, I believe that the moment result in the output grapher of Revolution:1 is what you're after. This should take into account the inertia of the moving parts in the assembly as well as the 0.45 friction coefficient drag from the pungers => Top in the 3D Contact Joints.

I hope this helps...

Thanks, -Hugh
