How can i make a Cam and Rolling Follower using Simscape?

Asked by Jacob Fackelman on 9 Oct 2012

Hello im trying to model a cam and rolling follower in simscape such as the link below shows. http://ocw.metu.edu.tr/pluginfile.php/6886/mod_resource/content/1/ch8/sec4/img2.gif

My current attempt to model this is by using a point curve constraint for the rolling follower body with the curve being the points going around the circumference of the roller. And a second point curve constraint with the curve representing the cam body. I then connected the two points with a shared environment block.

The roller follower is on a prismatic joint to move only up and down. While the cam is on a revolute joint to rotate with a joint actuator providing a torque.

My question is can i use these two point curve constraints, and shared environment block the way i have described and should i be using periodic, knot a not, or normal configuration? Or is there a better way using other constraints or methods?

Thanks this is my first post on Mathworks.
