Postby josegegas » Thu Nov 14, 2019 1:06 pm

The first steps using my MBDyn + FreeCAD workbench to do a bit more complex simulations... very exiting!

BTW, there's a video embedding tag on the forum.

Hi Jose,

Nice Animation, but your construction dosn't work... Have a look at the Axis of the big gearwheel. ;)

For reference, the development thread is here, FreeCAD as pre-post procesor for MBDyn.

Sorry, what do you mean by construction?

Hi Jose,

i don't know how you label the single parts, so it's not easy to describe... I made screenshot and put a red mark at the shaft where the big gearwheel runs on. At this shaft the purple signd parts will chrash.

I think herbk means if you were to physically build this machine, it would probably not work as this ideal model. Did you add collision detection yet, or not?
