Abstract:
The system design must be started from the concept with low cost and high performance. In this point, the topological shape of the structure is very important in the view of the structural rigidities and light-weight design.In this paper, the optimization methodology is presented in the design stage of the large optical mirror. We obtain the optimal layout through the topology optimization and then design the details through the size or shape optimization for structural rigidity.
Keywords:Optical mirror   Topology optimization   Structural rigidity   Light-weight Design   Microstructure   Finite element method (FEM)   Material density
