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:

this is mv of theme song of a movie that i watched recently, enjoy.

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.

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.

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  .
