An improved adaptive constraint aggregation for integrated layout and topology optimization
We present an improved adaptive constraint aggregation approach based on the KS function. Steffensen iteration is used to obtain better aggregation parameters. The improved approach is applied with the finite circle method to avoid the components overlap in integrated layout and topology optimization design. Multi-point constraints (MPC) are applied to establish the interconnections between movable components and supporting structures. The improved approach can handle the constraint aggregation and the integrated optimization well.
