What you think of this simulation

[gurangax]

Greetings all

Just want to share you a simulation I made on May. Maybe will help some of you guys. This is just to show you the idea of it. I found it hard to simulate a chain so I put the torque at the center of wheel.

Many thanks.

Hi gurangax,
nice wheel,
but did you apply a torque onto the main wheel ?

Can you also show this without the torque on the main wheel ?

Could you please post the WM2D file ?
The fixing point joints of the blue bars on the main wheel
are an error source.
Better use 2 pin joints for this.


Could you please switch on (show) the Center of Gravity for the
3 weights ?

Many thanks.
Regards, Stefan.

Your download limit has been reached. Could you post the .avi here?

Thanks,

connect small spheres with rods and set the them to collide with the larger body (blue).  Lots of work.  Use the rabbit function. Copy paste, copy 2, paste, copy 4, paste, etc.

Harti yes i put torque at main wheel. The reason is to show how it should work if we use chain instead of string in wm2d. I am not  good with wm2d, the placements of elements in the design is not accurate. I am positive that by using a chain like system will produce positive effects. I tried to make a chain system but the chain keeps jerking and the string becomes elongated, maybe bugs.

I post here the basic weights elements for the wheel along with the cg.
