movable slot joints

[cyberdust]

According to WorkingModel 2D, it looks it works.



After a turn clockwise of 30°, we get the position



The only problem seems to be, the slot joint, circled in the first image, must jump to the new position, so we get the initial conditions. This must happen with little energy to consume. The wheel itself, with all the waits of 10kg, will give about 10J in energy.

I have tested it with Working Model, there seems to be no problem. The only difficulty is the movable slot joint.

What do you think, will it work?

Does anyone have any idea, how to construct a moveable slot joint, as easy as possible and yet sufficient.

thanks, CD

Hi CD .. many of these weight transition ideas would work to give 'Out of Balance' [OOB] if there is a method to lift or shift weight along their slots at the appropriate time - in your model the lift occurs twice at 5 o'cl & 11 o'cl - the distance between opposing weights seems to be variable [from eyeballing it] so it doesn't look like they are interconnected in any way ? - the circular slot [offset] controls things I'm guessing which is what a fixed cam does.

My own experience [sims & hands on building] says that this will not work other than to move a little until finding its 'keel' position i.e. CoG position of lowest Pe of position where there is zero torque [i.e. balanced position with CoG directly below the center of rotation].

So the question is [forgetting about friction losses for the moment], what is the method of lifting the weights into position twice per sector that you use ?

P.S. Wm2D will show a 'runner' if there is no losses in the model - to approximate some real world frictional losses set air resistance to low [world menu] - that is a quick & dirty way of adding a small load to the system - its not perfect but a reasonable approximation - be aware that air resistance calculates forces on the vertical cross section of the pieces so when a lever is horizontal it has less than when vertical [N.B. imagine a small horizontal wind force constantly blowing across the page for an idea of the force effect of air resistance in WM] - in a many armed device such as yours this should even out pretty well but a one-armed device will surge because of it.

You can also add as attachments WM files here if you wish.

The weights (yellow circle, pairs of them) are on a slider, connected with slots to a longer blue rectangular shape. This shape again is fixed on a wheel (greater yellow circle on the background). The weights are lifted by the movement along a slot (blue greater circle). The slider is connected to this slot (small point). If I let it freely turn, it will come to a dead point of course. The point is, after I let it run for about 30°, I have to move the slot joint to its new position, which was also the starting condition. I have only a demo version of WM, so can post only print screens of it.

Add some air resistance & see if it moves 30 degrees or not - if not, then shifting the slot point position is redundant, IMO, as there is no extra energy demonstrated by excess velocity & momentum to carry it thru to recycle.

Hi, unfortunately this kind of wheel seems not working.
If you need I can upload a wmd2 file to built a more precise simulation. This file contains 16 weight-point on a circle guide but you have to built all the arms and lock the weights point on arm sliders.

Take a look to:

Welcome to the forum

The biggest problem is the dynamics of the weights transfer to the circle ramp and act as the only wheel. What you are calling the wheel becomes the guides.

Well, my wheel is not exactly the same as the Andy motor. There is only one joint per pair of weights, and it's gliding on a supporter. I think, instead of joints and slots, I will use disks. The idea is to use software, like the WM2D and with the help of software to guid the weights, so that there shall always be a torque, and hence a power output. Some calculations say the output is always greater than the input. That makes it an overunity device.
