“…Here, the six-bar model, sketched in Fig. 15, is composed of five design parameters -a, b, l 1 , l 2 , y -which are reduced to four because of the symmetry [20]. For example, l 1 can be expressed in terms of a, b, l 2 and y:…”

“…Most applications concern path synthesis problems [13,3,6,10,16,12,18] and the four-bar mechanism will constitute a basic example in the following. More realistic applications of function-generation synthesis will also be given based on the Ackerman steering linkage problem: a four-bar and then a six-bar synthesis [20,15,19].…”

This paper presents a novel approach to optimize the design of planar mechanisms with revolute joints for function-generation or path synthesis. The proposed method is based on the use of an extensible-link mechanism model whose strain energy is minimized to find the optimal rigid design. This enables us to get rid of assembling constraints and the use of natural coordinates makes the objective function simpler. The optimization strategy is divided into two stages: the first one relies on multiple partial optimizations and provides hot starting point for the second stage which involves all the variables and all the energy contributions. The question of finding the global optimum is reviewed. Instead, a simple algorithm is proposed to explore the design space and to find several local optima among which the designer may choose the best one taking other criteria into account (e.g. stiffness, collision, size,.. .). Two applications are presented to illustrate the whole process.

“…Others researchers have used modified mechanisms with an added degrees of freedom to synthesise four-bar and six-bar (Stephenson II, Stephenson III, and Watt II) planar mechanisms, as well as spatial four-bar and spatial slider-rocker mechanisms (Levitskii, Sarkissyan and Geckian, 1972;Suh and Mecklenburg, 1973;Alizade Mohan Rao and Sandor, 1975;Avilés, Amezua and Hernandez, 1994;Simionescu and Alexandru, 1995;Simionescu, Smith and Tempea, 2000;Simionescu and Talpasanu, 2007;Avilés et al, 2010;Collard, Duysinx and Fisette, 1910).…”

The problem of optimum synthesising of a mechanism to best approximate a function, while simultaneously ensuring good motion transmission characteristics is discussed. Distinction is made between the design variables that determine the shape of the input-output (I/O) function of the mechanism, and the design variables that affect the degree of overlap between this I/O function and the function to be mechanised, through scaling, mirroring and rotations in 90° increments. Examples are given of designing the planar four-bar and slider-crank linkages of a logarithmic scale, and that of a tangent-function generator. These are performed on modified mechanisms with an added degree-of-freedom, which substantially simplify the synthesis problem.
