| Abstract: | The updating scheme of design variables for topology optimization of monolithic compliant mechanism designs was derived by using variable density approach and optimality criteria method.Taking mechanical gain as the objective function of compliant mechamsms, tlae matnematmal moael for topological optimization designs was constructed. The objective function was described by artificial spring model and dummy load method and the sensitivity was analyzed by the adjoint sensitivity analysis method. The proposed methodologies are demonstrated through an example of a compliant gripper mechanism, and the prototype is manufactured to prove the validation of the conceptual design. |
