This work presents a systematic approach to improve the kinematic and dynamic characteristics of plate cam mechanisms by using the Bezier curve as the input speed trajectory. The analytical models of kinematic and dynamic designs for a variable-speed plate cam mechanism are derived first. Speed trajectories of the cam are obtained by employing the Bezier curve. Then, an approach to integrate kinematic and dynamic designs for motion adaptation and to reduce the input torque at the same time based on multi-objective optimization is proposed. Two examples are provided for the design models to illustrate the design process. Finally, an experimental set-up is established, and the data of related characteristics is measured to verify the proposed design for variable-speed plate cam mechanisms.
