You can put wheels on the ends. Just highlight all the wheels after you have made them, by holding down the shift key while you click on them, along with the main wheel, then go to "Object" on the top menu line and click "Do Not Collide".

Thanks for the tip!
I managed to make it with wheels on each pendulum now, but it’s not acting desirable. Pendulums keep rolling down the fixed wheel,  both on left and right side of it. Maybe when there are no wheels pendulums keep sliding over it while going clockwise and actually breaking if the big wheel wants to go counter clockwise?!
Anyway, I’m attaching this setup here also if someone wants to play with it and see what happens with wheels on pendulums.

@ Inquorate â€" I like your models and that latest posted on youtube is looking really promising. Looking forward to see those new improvements.

Hi All,

what happened to this simulation video ?

http://www.youtube.com/watch?v=LOcy11dkcgg

Has that been verified with other simulation software like
Phun or Algoodo ?

Has anybody worked on a real world model of this ?

Does it really work or were these only WM2D bugs ?

Looks to me pretty realistic.

What could be enhanced though is, that the weights could
be arrested when the swing out via clutches, so they don´t swing
back the the 4 o clock position, but stay tilted outside and make the wheel
overbalanced at the right side.

So any updates on this design ?

Many thanks.

Regards, Stefan.

Hello!

Just wanted to show you something I replicated in WM2D and posted on YouTube, but got a too big file and maybe no one wanted to try it for that reason.
It is an Interesting concept for harvesting pendulum pulling force. Apparently works in simulation software as Inquorate showed. Materials used are important for it to work. Pendulums have to be heavy comparing to the rotating wheel and there for from steel. Static wheel material is crucial for it to work. Steel and rubber work while other materials show bad or less good results. In his video pendulums are stopped with solid wall and I haven't managed to replicate that but had to use amorting part that is stopping pendulums less violent.
Keep in mind that pendulums in this simulation are mathematic vectors and that a point of each pendulum touching fixed wheel is probably a DOT and there for with probably very little friction. In real model this can be overcome with wheels at the end of each pendulum but in WM2D I’m unable to use wheels since mine setup would require third plain for them.
I’m attaching wm2d file for people here to play with or maybe even do more than just that …

Greetings from Srbija!

p.s. I apologies if this should be in some other part of forum, but I’m not so familiar with all its parts so moderators please move it if I made a mistake.

Hello, is there a free version of this software, wm2d, that we could download for open the file? Thank you
