According to the characteristics and requirements of achieving mechanical movement, a plate conjugate discal cam mechanism is designed. The simple harmonic motion is selected as the move- ment patterns of follower parts. Based on analytical method, the work profiles are designed for master and slave cam. The 3D solid models of the cam mechanisms are established based on Pro/E software. Exploiting to the Java language program, some key parameters of the cam mechanisms are calculated u- sing angular displacement 1~ increments as step length. The size calculation and optimization problems are analyzed for an associated follower slider linkage rocker guider mechanism and the design of parts and assembly connect constraints is implemented to the functional model of cams mechanism. Using the function of application programming of the Pro/E software, the kinematics simulation and analysis of the cam mechanism is achieved. A kind of technique and method can learn from quickly response design and simulation analysis is provided against cam mechanism, it improves design efficiency and quality.
