hi all,
well, I made a model to see the machine doing some work carrying a weight over distance.

Please can you post movies or GIF animations for those who don?t have WM2D installed ?
Many thanks in advance.

Regards, Stefan.

Okay, I just did install WM2D now finally to have a look at it and here is the first
converted movie attached.

Looks good so far. It is an AVI movie.
You must have the DIVX.com codec installed to view it.

Here is the next one, the Mini Version...

Enjoy !

Looks really neat !
Maybe the spring still needs a bit of different spring coefficient,
so the pendulum will really accelerate !

Now here is this thing on a waggon and it moves the waggon !

By the way, what is a good and natural setting for the air resistance ?
It was set inside the program, but maybe it is too low ?

I can already get a simular design withouta spring to accelerate to selfdestruction,
if I set the air resistance to Low speed and
at:
0.300 kg/ms

What is a good value for it that correspondens to a normal realworld setup ?

Here, play with it with the attached files.

Is the spring necessary? Or is it just another type of clutching mechanism (to bring the pendulum back)?

I know where to purchase some one-way clutching bearings, but I need confirmation that the physics aren't flawed in this software. Is there friction being calculated within the pivot points?

Anyone know of any other simulation software out there?

As the author of 'newenergymachine' replied on the other thread, springs and air cylinder are used in his machine for damping only... Though, I personally think they may be required for more than that.

But if hartiberlin's model is OK (could you post an AVI please?) without springs, then springs may not be required - and this is what 'newenergymachine' author wrote (without dampers his machine runs into selfdestruction).

As far as WM2D is concerned, I do not think $3000 software can carry invalid physics model. I would sue them if it were.

Hartiberlin the air resistance is set  at 0.7 kg/ms in the wagon version.
Cheers.

Well, that blows my spring theory (ha, ha)... I just deleted the spring from the mini model and it still works!  This is back to the simple Jhula model I began with!

I really don't know why it works.  I have attached an image with the pendulum centre of mass tracked, which may help to shed some light on it.  I wouldn't put it past being an artifact of WM2D (despite its $3000 price tag it does have errors, particularly in handling polygons).  Accelerating to destruction is something that I really don't trust since the pin joint on the pendulum 'drifts' and I am pretty sure that indicates a WM2D error.  I guess building a physical model is the only way to test it but it takes a bit of tuning to get it to run well.

hi all,
I have just discovered what is going on with this model. We all know this doesn't work in reality but we need to know why. Well the thing is called geometry. The problem is the L shaped piece. When you change it for another made by 2 rectangles joined then you get the correct result.
It STOPS faster than the original, coz you have more contact surface with air. Again bad news.

Cheers,

We have to study this model prajna made inside a big circle.

I didn't get positive results with that, xnonix (except when there was no air resistance load).  I designed it that way because I suspected the (polygon) angle bracket was causing the effect. Damn, I wish WM2D would sort their polygons.

I am still not convinced that the design will not work in reality; there is a possibility that a spring could bias the torque to one side.  Worth pursuing, I think.
