Abstract
In the field of mechanism design, optimum dimensional synthesis
plays a significant role. Focusing on path generation synthesis, the designer has
to find the most adequate mechanism capable of tracing a trajectory as similar as
possible to a prescribed one. The objective is obviously clear, but, in many occasions,
the methods dealing with optimum synthesis are quite complex and
with a lack of transparency. Consequently, students often get lost in the insights
of the optimization method and do not comprehend the influence of the different
parameters that can be included in the optimization, or important choices such as
enhancing the starting mechanism. Thus, they are not qualified to assess the validity
of the resulting optimum design. To overcome this lack of knowledge, we
propose a didactic optimum dimensional synthesis methodology mainly based on
the analytic relations of the mechanism under study and considering the interrelation
among synthesis variables. The guidelines of the procedure can be easily
programmed and different design criteria can be incorporated. A software named
GIMSYNT has been developed with this purpose, focusing on the slider-crank
and the four-bar mechanism.
