Compliant mechanisms achieve motion through elastic deformation. In this
work, we address the synthesis of a compliant cross-hinge mechanism capable of
large angular strokes while approximating the behavior of an ideal revolute
joint. To capture the competing demands of kinematic fidelity, rotational
stiffness, and resistance to parasitic motion, we formulate a multi-objective
optimization problem based on kinetostatic performance measures. A hybrid
design strategy is employed: an efficient beam-based structural model enables
extensive exploration of a high-dimensional design space using evolutionary
algorithms, followed by fine-tuning with high-fidelity three-dimensional finite
element analysis. The resulting Pareto-optimal designs reveal diverse geometric
configurations and performance trade-offs.
