Hello all
here under you will find a code in 9 phases to rotate a wheel by the mean of gravity+swing energy storing +torque recuperation of this energy
yesterday i tried it with only 2 fulcrums
by a single swing of 1 fulcrum (the other stay chopped on the wheel), i can get almost 1/2 turn.
the speed of the wheel is very important and must be controled to stay constant the power of the wheel depends not from the spinning speed but by the increase of the torque by changing the inclination of the wheel from flat (no rotation and no torque to vertical (max torque)
so i think that with 4 or 5 fulcrums we can harness the power of the Milkovic pendulum to spin the wheel à la Bessler
i have breefly discusssed this system in energeticforum.com under the Peter Lindemann thread "the mechanical engine" but i think there will be also interested and or experienced people here
Now i have to find a good chopping and releasing system and perhaps ::)
waiting for comments and suggestions
and now back to the workshop
cheers

woopy ; I find you wheel interesting. Using a ratchet paddle on a chaos pendulum effect. My biggest question is. How will the swing of the pendulum working with the ratchet be controlled?
This is a very awkward way of going about it. Much simpler is the double ratchet drive that is illustrated below. It drives the ratchet on the upstroke as well as the downstroke regardless of stroke length. It works very well with the Milkovic device converting the irregular oscillating movement into rotation. Sorry but no overunity though.

Laurent,
I have had a blast simulating these types of designs with WM2D. Have you considered that? It would be fairly simple to do but you would probably want to have the components drawn up in CAD so you can import them as DXF files. The simple drawing tools available in just WM2D make precise work with complex geometries quite difficult.
If you do not have these capabilities I can try and work something up for you later in the week. I should have some time on Wednesday or Thursday. In the meantime, you could get a copy of the WM2D demo on a machine that can run it so you can view the sim once I send it to you. Unfortunately I have not had much luck with the video export function of the program.
A simulation is not perfect, but if no OU tedencies are apparent in the sim, I don't think a build would show more potential. Plus it's a great way to try many ideas quickly as well as find what optimizes even those that do not work.
Thanks,
M.
@ mondrasek,
You are right, the video function in WM2D is not much chop. I found though that if you leave all colour rendering out and work with outlines only it's not too bad.
For what it's worth.
Hans von Lieven
Hans,
I only tried it on the Lindemann concept, and that was 99% outline, but heavily poupated with complex shapes. I thought it might be the limitations of my computer here at work. Didn't bother to try on my home system. Shame. I thought it would be nice to post video's of simulations especially since others had posted video's of animations. I know I enjoyed seeing how the program predicted elements would interact, even though the entire concept performed so poorly.
So you know of no fix within WM2D? I might have to fire up a video capture program if this comes up often.
M.
I don't know of any fix, sorry. But you are right, on the more complex arrangements WM2D has a tendency to shit itself and not only on the video rendering either.
Unfortunately its the best of a bad lot of simulators >:(
Hans
@ grayone
in this design i don't use chaos pendulums but on the contrary the aim is to get a very regular swing by controling the speed of rotation
thank's for interest
@ Hans
pleased to get your attention
can you detail your design as i did in the above code i mean could you make a phase after phase description of your drawing's code so i can better understand thank's
@Mondrasek
i did use WM2d to simulate a similar systsem (if you go to "energeticforum.com° and Peter lindemann "The mechanical engine" thread you will see that i got a really impressive simulated result ) but than i built it it and it did not work :-\
that's why i build every thing and my goal in this topic is not to know if WM2d is good or not but to test and feel the real thing and share the results
@all
the cost of this proto is about 20 bucks and 2 hours of work so please feel free to go on
i can say you that when you feel the swing and induced movements with your fingers you understand much easier what is going on
all the best

@ woopy,
This is really very simple. Both arms are mounted on the same axle as the wheel and are free to turn. When the arms go up one engages the ratchet wheel as the other one idles, the reverse is true on the downstroke. The wheel turns in one direction only, variations in stroke length don't matter.
Hope this drawing is clearer.
Hans von Lieven
I would assemble it like this
Hans
@ hansvonlieven
thank's for explanation
it is a very good idea to harness the Milkovic2 stages pendulum power and to perhaps measure if there is more output than input on the swing as claimed by the inventor
but what i am trying to do with the beslaurentius code is to use the gravity (not a push as per Milkovic system) to swing the pendulum and store the energy of this swing and use it back with the ratchet to motorise the wheel
until now with a single fulcrumswing the wheel turn just less of a 1/2 turn so if every thing goes " right" and as 1 single swing give almost 1/2 turn i would be inclined to think that a wheel with more fulcrums could close the loop ;)
but don't worry Hans so long i have not made it, i can only dream to this possibility and as you can see in my previous post i made a lot of experiments that would have work in my thought but did'nt in reality
and now back to the workshop for the best :) or the worse :( anyway there is always something to learn ;D
cheers

G'day Laurent,
I have just sent you a PM. As to the Milkovic thing, I have done a lot of work on this and have, like all the others, not found anything exciting. His theory is wrong and he is a bit of a scam merchant. He knows it's not overunity, that is why he is still pushing it with his finger after all those years.
Hans
@ Hans
very good info on your PM
as per Milkovic i don't know if he is or not overunity
but for today what is a good new is that i put in a small idea on this forum and thank's to you i got back a great info this is perhaps the ideaoverunity not so bad so far :)
and i go on the hard way with the swing accumulation of energy on my wheel
cheers
Laurent

Laurent,
As I said before: "A simulation is not perfect, but if no OU tendencies are apparent in the sim, I don't think a build would show more potential. Plus it's a great way to try many ideas quickly as well as find what optimizes even those that do not work."
There are many paths from a concept to an actual constructed device. After design and before a build a simulation can be a very useful step. It can help to optimize a design as well as validate and predict performance. But of course a final build is always necessary since even the best simulations are approximations. And it is fairly easy to make devices in a simulation work better than in real life (where they might not work at all) since you can choose material properties that are not available in the real world as well as manipulate forces like friction and air resistance to your advantage. But I believe it is more likely to produce a sim that works while the real device will not than to produce a real device that works when the sim fails. At least if the sim is produced properly and the software is written well.
I've attached a simple sim for what you showed at the beginning of this thread. Good luck with your idea.
M.
@ Mondrasek
hoaooowww ! :o
if in this forum there would be more people like you , i mean that stay on the thread and directly bring corresponding stuff every thing woul get much much better
your sim is fantastic and is very close to what happens in reality on my bench and correspond with what i can feel with my hands bravo man bravo
i suppose that you know WM2d very well and please go on with so excellent sim
and of course i can not prevent me to ask you please do the same but this time with 5 fulcrums
thank's a lot for sharing
Laurent
Laurent,
Here is the updated sim. WM2D is having much difficulty now that there are so many more elements to calculate.
In the case of this type of wheel, if you cannot get it to run with only two mechanisms at 180 degree spacing, adding additional mechnisms will not make it work. In fact, it will work even worse. Likewise, if it were to produce a usable output torque with just the two mechanisms, adding additional mechanisms will increase the output torque.
Thanks,
M.
@mondrasek
back for along journey i can only thank you to organise that sim for me and of course for all the interested people
i have a different idea on the 2 pendulums versus more pendulums
as , on my practical wheel, when the 2 active pendulums are stopped ,this happens at around 2 and 8 o'clock and at this points the 2 pendulums are as i would say "engaged " for the next step to go arround they need a slight push to go
that's why i think that the challenge is to get the the power of a the back track pendulum power at 4 o'clock ( in the mean time the counter pendulum at 10 o'clock need almost no energy to travel)
i am something tired now to try your sim
i will be back on the thing this week end
so may i ask you to organise a 3 and 4 pendulum sim so we have all the possibilities thank for your patience
and if it turns champaign ;D but no illusion must be the rule ;)
cheers
Laurent
