Abstract
The paper introduces a new design method for the synthesis of compliant mechanisms. This method is based on the optimization of the distribution of compliant building blocks within a given design domain. Building blocks are modeled by elementary frame ground structures. The topology, dimensions, material, contacts, fixed frame and actuators of the optimal compliant mechanism are generated automatically using a multi objective genetic algorithm such that the force/motion ratio is maximized. The set of optimal solutions is explored by using the notion of Pareto optimality. An application of this design method is tested on an actuated compliant mechanism with two output degrees of freedom.
