About Conjugate Cams

Why add a Conjugate-Cam FB ?

When there is a one Cam-Profile and one Follower, the normal procedure is to select the 2D-Cam as the Power-Source for the Follower-Part.

However, when there are two Cam-Profiles (on one Cam-Part) and two Cam-Followers (on one Follower-Part) - to give a Body-Closed Cam system -  the Contact-Force and Power will usually move from one Follower to the other and back-again, perhaps many times, throughout the machine-cycle.

In this circumstance, we use a Conjugate-Cam FB.

Then, after you edit it to select the 2D-Cams, you can select the Conjugate-Cam as the Motor-Element in the Configure-Power Source dialog-box,

2D-Cam: Elements, Parameters, Analysis, Coordinates

1.Add a 2D-Cam - see Add 2D-Cam

IF the new 2D-Cam is will be a Conjugate-Cam (Body-Closed Cam) then

1.a. Add Conjugate-Cam FB - see below

1.b. Edit the Conjugate-Cam FB to add at least two 2D-Cams - see Conjugate-Cam dialog-box.


2.Select the 2D-Cam (or Conjugate-Cam FB)  as the Power Source for the Cam-Follower - see Configure-Power Source


3.Review the 2D-Cam's Display, Properties, Cam-Life, and Roller-Life ... - see 2D-Cam dialog-box


4.Add a Cam-Data FB - see Add Cam-Data FB

5.Select a 2D-Cam to link it to the Cam-Data FB - see Link the Cam-Data FB to a 2D-Cam


6.Analyze 5 different parameters for the 2D-Cam - see below

7.Calculate the Cam-Coordinates - see Cam-Coordinates dialog



Preparation: The elements in the model before we do Add Conjugate-Cam FB:

Two(2) 2D-Cams on one Part. E.g. a Rocker/Crank

Two(2) or more Follower* on one(1) different Part. E.g. a Rocker

The 2D-Cams must display only the Inner or the Outer cam-profiles.

See 2D-Cam dialog-box

* Rollers and/or Flat-Faced Followers.
