Abstract

Optimal synthesis of mechanisms generating open trajectories based on non-linear position problems R. Sancibrian, F. Viadero, P. Garcia & A. Fernandez. Department of Structural and Mechanical Engineering, University ofCantabria, Spain. 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
