simulation testings used for future reference (actually my mind still in holiday mood, so only choose stuff that don't require thinking & it's easy to complete)



Take a break:

Hi Helloha,

I've been enjoying your different experiments with overbalanced wheel designs. It's interesting how one change can make a huge difference.

The movie scenes had very good music, cinematography and choreography. :)

I have a file if you want to test or anyone else that has access to a 3D physics sim.

I used Unity3D but the physics solver is geared as a game engine so it's not realistic to base results on. I'm wondering if a different solver will give different results.

The simplified model is based off the patent description of the Mann Gravity Mover.

http://peswiki.com/index.php/Directory:Mann_Gravity_Mover

It sounded like tapered bearings pivot on the bottom with a tapered bearings on top and a arm with the ends as giant ball bearings that rides along this. So the taper friction values should be about the same as low friction bearings.

I have the full model attached it is a .obj file. All that needs to be done is just setup physics on the five objects and create a fixed joint from the arm to the weight. The picture shows the setup. Then just play with friction/weight values. You can also try moving or scaling the size of the top and bottom taper.

Take a break. ;D

yet another simulation testings for reference. The two link above are based on same model, i just break it into two parts.

the model is based on this http://youtu.be/y2EhDPqiEi0 (this model had been on cold shelf for some time, might as well made use of it)

another presentation on the drawback of using ramp

http://youtu.be/m9u3OYmi7YY

initially intention is to design a failsafe for the previous ramp problem http://youtu.be/p5c1NKIsEbc, but end up create another problem  :'( , and also didn't get to see the failsafe in action. sigh  :-\ .

a design concept using magnet and magnetic shielding, but no youtube video, as i can't do simulation as the software does not have magnet feature, not to said magnetic shielding, ..... also it's still just a design concept.



Take a break:

been reading the Belt and Pulley Devices http://www.lhup.edu/~dsimanek/museum/themes/pulley.htm, interesting so did a model of the device.

try some simple simulation as cannot do the sim for gear belt, using cloth to act as the belt, but cloth tend to stretch and some other problems.... bottomline don't think it's possible to do a full simulation of the belt/pulley device. (also not uploading the videos to youtube as it's not presentable)

a small idea (basically like an hourglass), focus on an alternative methods for the human powered, beside the classic bike generator or hand generator (which is very tiring).

based on this model http://youtu.be/UOLPuvsXe9I, but reduce the number of weights/balls, remove the outer shell, slim down the length of the wheel.
