Optimal synthesis of crank-rocker mechanisms with optimum transmission angle for desired stroke and time-ratio using genetic programming

Dimensional synthesis of crank-rocker mechanisms applied to provide some desired values stroke and time ratio, is utmost importance for designing an efficient mechanism. In the manufacturing mechanisms, designers are further challenged by other design criteria, such as quality motion. this study, a novel approach based on genetic programming (GP) proposed dimensional planar with optimum transmission angle over time-ratio. An analytical elaborated which leads interesting relationship length coupler rocker links. It is, therefore, advised that adopting equal lengths link link, one can guarantee optimality angle’s deviation ([Formula: see text]), ensuring Grashof condition. Consequently, through inverse modeling approach, GP method utilized construct explicitly mathematical formulas represent all sizes dimensions mechanism any both way, input-output data set consisting links input variables time-ratio output first constructed using pertinent equations. Indeed, simplifies greatly crack-rocker The has been kinematic A comparison between obtained results work analytic method, clearly illustrates efficiency approach.
