Abstract

Conventional mechanisms provide a defined mobility, which express the number of degrees of freedom of the mechanism. This allows the system to be driven by a low number of control outputs. This property is kept in case of compliant mechanisms with lumped compliance, which are obtained by replacing the conventional hinges by solid state ones. Compliant mechanisms with distributed compliance have, in general, an infinite number of degrees of freedom and therefore cannot guarantee defined kinematics. In this paper, compliant mechanisms with selective compliance are introduced. This special class of compliant mechanisms joins the advantages of distributed compliance with the easy controllability of systems with defined kinematics. This task is accomplished by introducing a new design criterion based on a modal formulation. After having implemented this design criterion in an optimization formulation for a formal optimization procedure, mechanisms are obtained in which a freely chosen deformation pattern is associated with a low deformation energy while other deformation patterns are considerably stiffer. Besides the description of the modal design criterion and the associated objective function, an application example is shown.
