Abstract: This paper studies the solution methods of optimal synthesis of planar mechanisms. The method is defined by using of pso techniques and a common kind of goal function which is used to find the appropriate dimension and to minimize the error and find the best mechanism with accurate Solution. The possibility of extending is the advantage of this method. Unlike others we do not consider input angle as design variable, because in those cases when many precision points are available, computation will increase without having exact solution. So we divided the path to some section and find minimum error between desired points and design points. Using this method, we can easily decrease the path error and processing time. Key words: Planar mechanism PSO algorithm Path generation Optimal Synthesis

The paper addresses synthesis of planar mechanisms approximating open paths. The technique is introduced and discussed on the example of the four-bar linkage, although it can be applied to a planar mechanism with four links as it does not refer to mathematical formulas describing the geometry of a mechanism. It suffices to know the trajectories of the joints of the coupler a point of which traces a required path. An objective function is proposed and minimized by the evolutionary algorithm. The synthesis of four-bar linkages generating arcs given parametrically including straight line and square angle are carried out. The results obtained prove that the method is effective.

## SYNTHESIS OF PLANAR CAM-LINK MECHANISMS FOR …

A novel dimensional synthesis technique for solving the mixed exact and approximate motion synthesis problem for planar RR kinematic chains is presented. The methodology uses an analytic representation of the planar RR dyad’s rigid body constraint equation in combination with an algebraic geometry formulation of the exact synthesis for three pre-scribed positions to yield designs that exactly reach the prescribed pick and place posi-tions while approximating an arbitrary number of guiding positions. The result is a dimensional synthesis technique for mixed exact and approximate motion generation for planar RR dyads. A solution dyad may be directly implemented as a 2R open chain or two solution dyads may be combined to form a planar 4R closed chain, also known as a planar four-bar mechanism. The synthesis algorithm utilizes only algebraic geometry and does not require the use of a numerical optimization algorithm or a metric on elements of SE(2); the group of planar displacements. Two implementations of the synthesis algo-rithm are presented; computational and graphical construction. Moreover, the kinematic inversion of the algorithm is also included. Two examples that demonstrate the synthesis technique are included. [DOI: 10.1115/1.4028638]

Most graphical and analytical synthesis methods for path generators require specifying the desired trajectory in a non-functional manner, by a list of points rather than a pure shape.
