Add friction in Dynamic simulation

Anonymous — Sat, 09 Apr 2016 11:50:02 GMT

I have Inventor 2014 student version installed. I'm trying to do the "Add Friction" section of the "Dynamic Simulation" tutorial. I've made the "Blade Set" flexible as per instruction 1. Instruction 2 says "As previously mentioned, the assembly has no friction yet. This step imposes friction on the prismatic joint. Right-click the Prismatic Joint for the guide and the Scottish Yoke, and click properties". In the browser there is no Prismatic Joint listed anywhere for the Guide or the Scottish Yoke. So, exactly what in the browser am I supposed to right-click and choose properties? Thanks! A screenshot of what I have so far is included.

1. In the image you attached you are in the assembly environment, not in Dynamic Simulation Environment.

2. Attach your assembly here.

Environments>Dynamic Simulation

I recommend that you go back and repeat Part 1 of the Dynamic Simulation tutorials - and pay particular attention to Step 1.

OK. The tutorial omitted the fact that I had to go to Dynamic Simulation. So, I right-clicked the Prismatic Joint for the Guide and the Scottish Yoke and clicked properties. On the dialog box I clicked the dof 1 (T) tab. Then I clicked the "Edit Joint Force" command. I then repeatedly tried to click "Enable Joint Force". The check box will not activate. What else have i done incorrectly? I did as you suggested and started the tutorial again at the beginning. Thanks for your assistance so far!

1. Post screen shot, or better yet - see #2

2. Impossible to say, once again you have not attached your assembly here.
