Modelling Foucault's pendulum attached to a cylindrical disk in Simscape Multibody
13 views (last 30 days)
I am trying to model a spinning disk attached to a rod in simscape multibody, as shown in the diagram attached. The disk is supposed to spin at a constant rate and cause the pendulum trajectory to shift, as opposed to going back and forth. The rod does not spin on its own axis. Please see this https://www.youtube.com/watch?v=pKGgICawAKc as an example of what I am trying to model, but note that I have a spinning disk instead of a spinning sphere.
I have also attached a draft of the model, but it doesn't seem to work correctly since I cannot see the pendulum behaviour and both the rod and disk are spinning along the vertical axis. Could you please help introduce correct translational behaviour into the system or share any similar models you may have done?
Thank you for your help.

Hi Jake - attached to this answer is a model I built that I believe models the system you describe. Please note the location of the sensor and the frame used to define the camera. They are both in the reference frame that is spinning.
