Design of coupled slider crank mechanism for orbiting motion

Abstract

The paper describes development of a novel orbiting mechanism. Target design is a shaking mechanism with a planar figure eight closed loop. Shaking dynamics depends on a cycling frequency as well on a reciprocating displacement. These two parameters are in the focus of preliminary design and analysis. Computational optimization and path definition were interrelated to core engineering work. Crucial novelty is an orbital motion created by a coupled slider crank mechanism. An academic package of the Solid Works Motion 2010 was employed for parts and assembly design, as well as for the subsequent mechanism analysis. The outcome design proved itself in operation with a smooth shaking motion over a closed loop and even more the uniformly distributed acceleration peaks within each cycle.
