High-speed cam design for quick-action linkage system

As a specially designed mechanism, cam is usually be used in many high-speed structures and mechanisms. Diverse geometric cam counters support for diverse motion applications, including the displacement, the velocity and the acceleration. This paper proposes a design of a high-speed cam which can be applied in a quick-action-based four bar linkage system. This variable high-speed cam is design by using the graphical combination of 5th and 7th polynomial cam curves. In addition, the kinematic model of a linkage system based on our proposed cam is constructed. Finally, the simulation results of the cam counter, velocity and acceleration of the designed cam are shown to validate the appropriate application of a quick-action linkage system.
