The purpose of this paper is to synthesize the structure of metal can squeezing devices with eight-bar links and triple toggle effects, based on the methodology of creative design.
The article presents design equations and techniques for the complete shaking force and shaking moment balancing of eight-bar linkages due to both linear and rotary inertia, except external loads.
