Analysis of a Six-Bar Linkage

Previously, K. Ogawa made an exhaustive survey on the synthesis of a four-bar linkage in which the locus of a point on the connecting rod was described systematically in a wide range of link dimensions. In this paper, the displacement characteristic of a six-bar linkage in the range of operation was analysed, when the driving crank made a complete revolution while the follower crank oscillated. As a result, the relationship between the form and its displacement became clear, when various forms of the six-bar linkage were given. It is expected to provide direct aid for designers in selecting a mechanism to produce a desired motion.
