Simple Devices & Experiments In WM2D

[Tinhead]

The parameter for rotation would be body(x).p.r ... where you have to replace x with the actual number of your object. Those brackets are supposed to be square brackets, but somehow this editor treats them as a special character ... ?
Just create a meter for rotation, position, etc. and in there you can see what parameter is used to access the value needed.

I will try to attach the formula reference, have a look and if you need more examples, just ask.

Cheers,

Rainer,
I uploaded it successfully. Looks like a good stuff.
Thank you for your help. I appreciate it.

Hi Dale!

I have experimented a bit with centrifugal/centripetal force and released a weight from a r = 4m big wheel.
Around 20 rpm an 1.5 kg weight flew out of the wheel easily, even upwards. Over 30 rpm it flew out with more velocity. At first sight I think CF can be used to operate with it in a clever way. The test was also very useful for me, and for my development of my own models. Thanks.

I will do a kind of spring ramp test at the weekend.

Regards,
Greg

   Hello Greg.
   Thanks again for the update and efforts. I am feeling a little helpless on this end.
  If I can do anything to help please let me know. Very happy to here that this might  help your concepts!

Dale,

I have finished a spring ramp test. As you thought, it is possible to push the weight back to the inner latch position. Works good.
My wheel is driven by a torque motor, and accelerating to 13.6 rpm, where the weight hit the spring ramp.
I marked the weight in question, and the ramp with green color.

Weight is released just before the collision, at t=1.55 sec
The torque motor is turned off at t=1.6 sec

The weight hit the ramp, and the spring push it back to the inner position.
RPM drops a bit at the collision event (by 0.7 approx.), but quickly gains back while the torque motor is turned off. This is at 13 rpm.

I can't test it at higher Rpms because the WM2D has problems with collision at higher rpms, usually simply ignores the collision. I can be very angry in these situations.
But weight return with greater force at higher rpms, sure.

Important things:
The diameter of the wheel, the mass of the weights, the position of the spring ramp, the force of the spring, and the rate of velocity must be designed together, in relation to each other to find the best and most efficient version of the return process.

Here is a sample picture:
