WOLFRAM SYSTEM MODELER
Model exploring three different cam shapes.
|ˇ Introduction||ˇ Dynamics|
This model shows three different cam designs that have been generated using the Wolfram Language.
In order to get the full experience of this example, you need the following:
These pages show an overview of the example. For the full example, open the accompanying notebook CamFollower.nb.
The follower is modeled as a spring that is attached to a fixed point in one end and that is being pressed against the cam in the other. The cam translates the roterary motation that is being supplied by the rotator to a translational movement that acts on the follower.
To simulate the model, perform this step:
Explore how the follower position changes over time by plotting the variables roundCam.follower.flange_a.s, pointyCam.follower.flange_a.s and harmonicCam.follower.flange_a.s
These variables are shown in the default plot of the model:
Cam designers wants to minimize the jerk (the derivative of the acceleration), in order to minimize the stress and wear on the cam. Plot the jerking movement and compare it to the follower position. To add a graph of the jerking movement, follow these steps:
You should see something like the graph below.
