12 times more output than input, dual mechanical oscillation system !

[zoelra]

I have not built models using weights larger than 10lb, as the CF at 6 o'clock (either 20lb or 40lb depending on drop height) was at the limit of the materials used.  I prefer lighter builds as you can see the effects of friction and CF more clearly.  IMO the current Milkovic design does not provide the answer but other modifications may prove useful.  Only time and hands on testing will provide the answers.

@ libre,
I am sorry that I do not have a huge research facility and staff to help me. I have built all my tsmo projects with my own money, my own time, and by myself. I understand that you want scientific results, but, Do you think I keep building these because I am some kind of idiot? Milkovic has never had his patents disproved. Let me assure you that when you are moving a pendulum that weighs 100lbs., like your dribbling a basketball, you will think differently of milkovics ideas.
If you look at the recent posts about the overunity in pumping water, I would have to say that I came up with similar results.
This is the reason I have been building these and the reason I will continue to do so.

Peace all,
Greg

Milkovic's two stage mechanical oscillator - oscilating vs. rotating pendulum test
by Trajkociklista (YouTube)

What we have here is a quick and dirty mock up of Milkovic's two stage oscillator.

I just used what I had laying around, and as I always have few bicycle components.

Its no secret that if you remove one pedal from the free rotating bicycle crankset,
once you start it and get it to rotate, it takes very little to keep rotating, just a touch of a finger between the last quarter of it's rotation before the top spot.
So I figured that that might be much easier type of pendulum motion to keep energized.
Just a simple motor with a chain/belt drive could be be rigged up to drive the pendulum axle.
Now, as I've noticed while spinning a bicycle crankset with a pinkie, is that the rotating gives much more "kick" then the swinging one, I wanted to see if it would result in more powerful oscillation at the other end. And as you can see, it definitely does.

Here are the facts and the math:

Lever has 1.61 ratio (the golden ratio! just a coincidence really, since I'm using a recumbent bike frame here (buy yours here: velomotion.weebly.com )
it's just accidental that the ratio between the lever pivot point (actually an idler wheel mounting point) and the rear wheel axle/crankset axle is exactly 1.61, with 89cm from the pivot point to the rear wheel axle (center of the mass for the wheel, could have used a weight, but I don't have any) and 55cm to the crankset axle.

Pendulum(a pair of bicycle pedals) weights 533 grams, rotating on a 170m crank arm.
Weight is a rear wheel, with a weight of 1700 grams.
So with a 1.61 lever ratio, we need 2700 grams on the pendulum side in order to balance the seesaw, which I confirmed by placing a precision scale between my hand and the end of the lever, which showed 2700g needed to balance the seesaw, where wheel starts to lift off the ground as soon as the scale hits 2000g So, in order to lift the wheel, 533g pendulum will have to create a minimum of 2000g, or ca.4 times more then it's own weight, and 5 times more to balance the seesaw.

Then I got the pendulum oscillating, helping it with a slight push of a finger.
I can not precisely determine how mush do I need to push it to keep it oscillating,
because of all the motion, but it definitely feels more then the force that helps it keep rotating.
To keep it rotating i'm just slightly touching the crank near the crank axis, and about the same pressure on the scale shows around 300 grams, and that's just on the last quarter before the top spot of rotation.

With oscillations, as you can see, wheel did start to go up, but just a little bit.
And then I start to spin it and the back and goes wild
When I give it proper speed it's around the balancing point, or ca. 2500g (or even more, hard to tell with an unstable dirty rig like this, need to make it fixed and stable)
out of a 533g pendulum + 300g pulse to keep it rotating.
But as you can see, when the wheel starts to really kick off with the raised rpm of the crnak, the amplitude of the pendulum gets really serious, much more then the 2700g nedded to balance it.
At that point there is a problem with stability of this flimsy mock up, and I also have trouble keeping that rpm with my finger as I just can't follow the crank fast enough
to give it a push when it needs it.

Anyways, this thing definitely works as advertised, that's pretty obvious I think, and it's just the question of how much amplification are we getting here.
But whatever it is, gravity/inertia/centrifugal forces really do some serious work here,
so in any case we get much more then we paid for in terms of power needed to keep the pendulum rotating, for the work done on the other side.

Great invention from Mr. Milković ! It can have so many practical purposes.

pendule milkovic (mauvaise configuration)
by freedericklane (YouTube)
http://www.youtube.com/watch?v=Y4bNOUqKWgc

Dispositif sur le principe du pendule de MILKOVIC .Ces deux montages ne sont pas bon car le cycle de l'embiellage de la roue ne correspond pas au cycle du mouvement de va et vient de l'effet Milkovic qui n'est pas sinusoïdale.
Un bon moyen pour récupérer la force en mouvement rotatif est d'utiliser une "roue libre" à cliquet d'une roue de vélo par exemple.

Il est intéressant de constater l'échange d'énergie entre le pendule et la roue d'inertie dû à la désynchronisation des deux mouvements(rotation,pendule) qui sont indépendant.(on l'entend au bruit)

GOOGLE TRANSLATE TO ENGLISH:

Device on the principle of pendulum Milkovic. Both mounts are not good because the cycle of the crankshaft wheel does not match the cycle of movement back and forth of Milkovic effect is not sinusoidal.
A good way to get the strength to rotary motion is to use a "freewheel" ratchet wheel bike for example.

It is interesting that the energy exchange between the pendulum and the inertia due to the synchronization of the two movements (rotation, pendulum), which are independent wheel. (You can hear the sound)

[Paul-R]

Both mounts are not good because the cycle of the crankshaft wheel does not match the cycle of movement back and forth

...which is saying, in effect, that it is not "in resonance".

It needs to be "in resonance".
