2015 FIRST World Championship Creo Modeling Challenge #3 - 4 Bar Linkage Mechanism
Creo Parametric CAD Modeling Challenge
For this third Creo Parametric CAD modeling challenge, you will be creating a full assembly of the 4 bar linkage shown below. You need to know basic Creo Parametric assembly constraints, Kinematic constraints and assembly structure to complete the design. It is a fairly simple model to create, but you will need to master Creo Parametric Pin constraints to make it work correctly.
Create sub-assemblies for the fixed and moving components with equally spaced linkage arm mounts
Assemble the fixed sub-assembly first and make sure it is grounded
Add all the hardware at the end
Set limits for the first control arm to make sure the mechanism does not freely rotate through 360 degrees
Use a second set of constraints to connect the moving sub-assembly to the linkage arms
