Before we start this tutorial, add this cam mechanism in a new file, or to a new Plane in an existing file.
|•||It is a 4-bar mechanism. The length of the short-rocker[left] is 100mm ; the length of the long-rocker[right] and the coupler[horizontal] are 200mm.|
|•||The Pin-Joint in the Base-Part of the long-rocker is at [200,-100]mm. The centre of the Cam-Shaft is at [100,100]mm.|
|•||There are two cams and two cam-follower-rollers. The rollers are ø40mm|
|•||The two cam-follower-rollers are fixed to the coupler of a 4-bar mechanism, and offset from the coupler's centre-line by approximately 10mm.|
What are the Design Objectives?
In this tutorial, we use one Design-Set to find a solution to two design objectives.
The design objectives are:
|1.|| The 2D-Cams should have the same maximum radius. |
|2.||The minimum radius-of-curvature of each 2D-Cam should not be less than 20mm.|
Note: I apologise that this is a very boring design objective! However, the tutorial does show you how to add, edit and use Design-Sets.
