The Mechanical Engine

[Vortex]

Well, it's not a fluke, I've created 4 running devices ..
but that depends upon your definition of running?
I think the software I'm using is broken.
It generally stops processing if I try to monitor things.

All of my devices are unbalanced but not by design.
They are Chaos devices by design.

I'm using rubber and steel to get some extra kick out of the movements.
Steel on steel is too much kick.

I didn't know what I was doing when I started, so all these except the last one are very large devices..
1st device, WildOne, has 8 - 2 meter length pendulums on 5.5 meter across arms, takes 192 frames before it takes off into hyper space. The software is screwed up?
This device runs not in one direction but both., back and forth.

The 2nd devise, Wiggler, is a 8 double-pendulums on 5.5 meter across arms. Both parts of the double-pendulum is just over a meter each. This one just wiggles back and forth mostly and at 900 seconds it's still wiggling like at the start.

The 3rd device, PacMan, has 8 double-pendulums on 5.5 meter across arms.
First section of pendulum is one meter and second is 0.39 meter circle.
This one works like the Wiggler but blasts off into space.

The 4th one is a copy of Inquorate's mounted on a two foot rotor.
Hey, a small device
I couldn't get the device to rotate with a slow down bar installed.
Very slow rotation.
This is the only device that rotates only in one direction, once it gets going.
Since it is so hard to create these devices with this software I used
no collision on the pendulums so I could get the number of pendulums
on the devices without having to rebuild the deive.

The WildOne and PacMan in the virtual world hang together, but in the real world they would fall apart from the forces. that must be why the software keeps stopping.

Would been nice to try these designs on some other software and see what comes of that.

I'll use a wheelbarrow wheel axle and bearings for the centre, planks for the arms, skateboard bearings for the pendulum axles with 1/4 inch bolts thru them.

Excersize weights for 'flywheel' etc. Wheels on the ends of the pendulums?

Eccentric wheel will be adjustable on the main axle.

Damping bar has to be more adjustable, another bar it can be moved left and right on?

And a bicycle pedal cog for chain to small generator.

And about half the size indicated, so I can work on it in my loungeroom. Oh and 8 arms, not 4 - was keeping sketch simple.

Love and light.

Edit; my wm2d file is 17mb if anyone wants it; also I have Woopy's many pendulum large eccentric wheel version's file, about 2 megs. I guess springs take up lots of memory in a save file..

You may want to consider using a round piece of plywood, or two sandwiched together (good flywheel), for your wheel. This configuration is much easier to get your layout set up, and evenly arranged on. You can get precut circles at many hardware stores, if you don't, or can't cut it yourself.
1/4- 20 bolts make good hangers for the weights. You won't need bearings if you use nylon fishing line and fishing weights. They will swing virtually friction free on the smooth part of a bolt. Or drill a hole through the bolt and let the line just flex. This arrangement also allows easy adjustment of the pendulum length, which will certainly need adjusting.
Your design is so simple, I may have to build one of these myself.

I hope you do that Ted. You also might want to consider using plastic bolts. That way the weight of the bolts wouldn't be affecting the device nearly as much. They would also be much easier to drill through just as you suggested... as long as the drill bit doesn't get hot enough to melt the bolt. Fast drills like that wouldn't likely reach that amount of heat... since plastic is soft anyway.

I found the pictures you posted earlier very interesting and detailed. Bike chains and all, but again had you used plastic chain you would not need to factor in weight of chain. Just a thought. All the metal parts added are likely throwing a monkey wrench into the finished prototypes that are just about impossible to calculate all the negative versus all the positive changes they are introducing, and then not even uniformly but seriously position-dependent.

Plywood and fishing line and plastic

Good ideas !

Also Aluminum Rivets Already Drilled

Thanks, funny little man who bows a lot & smiles. I was just recalling also seems I once saw some rivets you can buy that has a hole already through the middle. You might could avoid drilling the bolts altogether. If you ever needed to take one out or move it you would need the drill then, take one side down. The aluminum ones are especially lightweight.

If I used plastic bolts or plastic chain, the whole thing would have fallen apart.

Modernizing Bessler's wheel?

I've been thinking... Most of these computer sims have frictionless bearings on the pendulums right? And maybe the pendulum will stop swinging on their own by 7o'clock.. Or at least be substantially reduced. Hence preserving the difference in downward motion difference on each side of the wheel.

I've also been thinking about the cost of delaying the pendulum's movement with the eccentric wheel at 11:50 to make the pendulum swing, and how it limits the weight of the pendulum versus the weight of the flywheel.

What if we used a bedini coil to push the pendulums at 12:00? - would the return from gravity / centrifugal force be more than the cost of bedini coil pushing the pendulum, keeping in mind the efficiency of capturing the radiant spike.

in theory, it could very much still be cop > 1

Perhaps I should have used a better word than just "plastic". I was thinking more like nylon. I understand nylon is right tough. But the man doing the building is the one who has ta make the call. You also shouldn't mix plastic against metal gear teeth. Also, any time you have nylon rubbing through nylon there's going to be an inhibiting friction there that would be undesirable => you wouldn't want a device shaking AND building up heat. Darn thing might self-combust.

Excellent points Ted. You're very thorough.

Nylon screws have their place, I've used them many times, but they have very little structural strength. Steel bolts, around the perimeter of the wheel, will only add to the mass of the wheel. This is the same with my steel chain. As long as it's reasonably well balanced, no further calculation is required. All the steel is doing is adding weight to the flywheel effect, which is basically desirable.
These wheels can, and should be built with easily obtainable parts. A few pieces of wood, a bearing or two, some bolts and screws, fishing line and some weights make up the majority of the project. Anybody with basic construction skills could build one of these wheels. There is nothing complicated or mysterious here.
Once built, it will take some tuning to get it to run right. Things will have to be adjusted and tweaked, even redesigned and rebuilt. This is absolutely normal.
Computer simulations are fine to a point. Unfortunately, they rarely give an accurate representation of reality. They will get you in the ballpark, but that's about it.
The only tricky part I see with this wheel is the damping and swing delay portions. Nevertheless, these are merely mechanical issues that need to be designed and tested according to the individual wheel.
Imagine what your friends and relatives would say if you had a working model on your coffee table rotating all by itself throughout their visit. Then you could show them the big one in your garage that powers your house.

Michael, at the bottom of the first page after you go to renewable energy there will be a "NEW THREAD" button just like the reply button you hit to post.

thanks Mark I have now worked it out, but I have one more question , how do I move the post that I made to the other site, or may be it can not be done!!!!!!!!!!!!!

I hope I can put some input into this thread as well, I do have a time difference with the USA as I live in Spain, but I am English and a Bsc in Industrial Engineering and have worked a lot in the energy field, now semi working and so I can devote some time to R & D. I do have patents in the field of heat transfer, all be it has cost me more than I have gained, I will never do it again, all will be free to the world

That would be very funny Ted, having a coffee table toy sitting there, visitors asking questions, after a while taking them out to meet Papa Bear.

Computor simulators are written by humans with a text book education and so in this field they will not give you an exact account of what will happen because they do not take into account the abnormal, they are text book programs, a waste of time.

I find the best way to look at things is like this, imagine a round disc, a clock face, at 12 you want to start the maximum external weight on the disc, at 3 is when this weight has been exhausted, from 3 to 6 is when you need this weight to move to the center axis or as close as possible, at 12 you want this weight at the edge of the disc again so as to start the cycle over again.

Now you have more weights behind the first so part of the energy of the following weights has to be used up to move the preceeding weight to the center of the axis, if this is done then you will have a continual motion. the trick is to design a system, with low friction, to move these weights at 3 to the center of axis before 6 on the clock face

It helps if you add some cheats.

It helps if you add some cheats, as many as you can find.
