Abstract
In this paper a method for more effective structural error quantification in
mechanisms generating open trajectories is presented. Generally, mechanism
synthesis methods compare the desired curve with the generated curve, taking
the mean square distance between the two curves. However, none of these
methods is suitable for general application and the problems tackled must fulfil
some requirements, for example to be a Grashoff mechanism. Furthermore, to
achieve an acceptable final mechanism requires starting the iterations with an
initial mechanism that generates a coupler curve similar to the desired one. All
these problems are increased due to the difficulty of selecting the most suitable
part of the curve when the desired path is an open curve a
