In this work, synthesis of compliant mechanisms for a variable-geometry forward section wing concept based on geometric nonlinear FEM is presented. The path-generation objective function formulation for topology optimization of compliant mechanisms is implemented in a custom optimization code. Moreover, the code is extended with other existing topology optimization methods, such as a multiresolution topology optimization scheme and partial differential equation based filtering techniques. The implementation is tested with generic example problems. A new stacked compliant mechanism rib concept is introduced for the morphing wing application. For this concept, compliant mechanisms are designed under consideration of stress constraints.     «
