Abstract

This paper summarizes a new capability in the topology optimization, which employs an advanced substructuring technique in the multi-domain topology optimization for the purpose of designing a complex and practical mechanical system. In the substructuring method, a structural system is divided into a series of substructures, which can be designed separately with the coupling of the subsystems. The condensation technique is applied to the substructures where the design changes are not considered at the current step. For the substructures where the optimal design is sought, the multi-domain topology optimization is applied in order to achieve the design objectives prescribed. The embedded advanced substructuring technique allows users to select nodal displacements and modal coordinates as generalized coordinates in the reduced-order models, and to use advanced Quasi-Static modes for high efficient modal analyses. Examples are illustrated in order to demonstrate the feasibility of the proposed technique to the topology optimization problem.
