Dynamic Simulation - Exclude from Simulation?

[Anonymous]

Hi everyone, is it possible to suppress parts or otherwise exclude them from an assembly when using Dynamic Simulation?  If not, can someone give me any tips on a workaround workflow for this?  I am working on a linkage which is mirrored along the centerline of the structure.  To simplify the analysis I want to analyze half of the linkage and use the values to analyze the whole assembly.  Any thoughts?

Hi Java,

you can create a rep of detail named "Dynamic Sim" where you will suppress the parts you don't need.

Thanks for replying.

I don't believe that will actually exclude them from Dynamic Sim. I did try that, and even if I suppress parts they still show up in the simulation in mobile groups, etc.

Yes, you have to believe it.

It will actually exlude them.

Can you atatch your assembly?

Here's the assembly.  If you could give me some general pointers about Dynamic Simulation that would be great.  I am trying to estimate the amount of force needed to lift this assembly using hydraulic cylinders using the "Unknown Force" function.  Thank you!

Hi,

as you can see  the part remain suppressed.

You can see it in the browser but ut's suppressed and not consider in the analysis.

For the rest, yes, you can do that study.

I can't show it now because it's not a quick job,

Maybe next week we will work on it togheter- Ok?

Hi! Yes, it can be done. You simply need to un-enable the component (part or subassembly). Go to browser, find the component of interest, and right-click on it -> uncheck Enable. It is basically taken out of the context and the component will look transparent to distinguish itself from other in context components.

Many thanks!

A cleaning and a simplification should be necessary to prepaqre the simulation

This is very helpful. Could you post the modified file so I can inspect it?

[admaiora]

Sure Javal.

Thank you very much for replying. Unfortunately I can't open this since I have Inventor 2016. Is it possible for you to save this as a 2016 version?

[admaiora]

i am sorry. i can't

Hey Admaiora, thanks for helping me with this.  Since you can't post 2016 files, could you give a short explanation of how you went about this?  

- Did you use insert joints for every pin connection?

- Did you use the Unknown Force function?

- Did you use the imposed motion function for the cylinder constraint?

  - How did you account for the fact that there are two cylinders pushing?

Hi Java,

here the assembly in the 2016 version, so you can study it by yourself.
