Design and Motion Simulation for the Virtual Prototype of Cam Mechanism

Traditional ways of design for cam mechanisms,featured by graphic method,tend to suffer from the drawbacks such as low efficiency,poor precision,long development cycle and high cost for the prototypes.Based on the inversed mechanisms principle,taking the knowledge engineering as the method and using CAD software as the tool,the parametric design of the plate-cam profile is carried out by the analytical modeling in the CATIA.A virtual prototype of a plate-cam mechanism is created and simulated,and the correctness of the method is validated through analyzing the simulation result,which provides an effective method for the efficient design and accurate analysis of cam mechanisms.
