The DOORS -- A Working Gravity Wheel in WM2D -- LET IT ROLL, BABY, ROLL!!

GraVITar
is it time for a physical simulation?
Throw down the specs and I will build it !![when you are ready]

Do you think you could make this? I picture the two outer wheels with convex rims and the middle wheel with a concave rim.

The picture below isn't to scale but should give you an idea of what I mean.

Hopefully, this will hold the freewheel in place. If not, I picture some guiding rollers on the sides of it.

Synchronicity HAS to be maintained for this to work[no slipping allowed?]
Gears would change things ?
Could more drive wheels compensate?

Hi All,
I quickly put something together as a WM2D file.

Well, it works infinitely, but only when you disable air resistance.

ButI had enabled Friction model under accuracy.

Hmm,. when air resistance is enabled, it does not work anymore,
so I guess it is a rounding error with WM2D...

Here is the file:

Stefan, I tried your setup and increased the mass of the oscillating wheel.

It worked with air resistance just fine.

you just have to experiment with different masses for the different wheels, also different locations, angles, etc.

Well,ifyou increase the mass,
you have to make sure it is not just some kind
of flywheel effect.

How many KGs did you make the wheel weight ?

As the wheel then has much inertia, it will
keep on spinning very long to see any change in
WM2D.

So better just try it first with 100 Gramms only weights or so...

Any gravity wheel is going to be part flywheel, just as windmills are.

I am trying to post a file but it's not working right.

The file has the DOORS accelerating from a reverse state.

It starts off going "backwards", stops, then starts turning in the "right" direction, steadily accelerating the whole time.

Both high air resistance and electrostatics are activated.

The oscillating wheel is 20kg and the rotational wheel is 100kg.
