Design Optimization and Testing of an Active Core for Sandwich Panels
Abstract
This report has two parts. Part 1 presents a study on design optimization and testing of a representative adaptive airfoil structure using a multi-objective topology optimization method SIMP-PP taking into account of both stiffness and flexibility requirements. The adaptive airfoil is designed using the "unit cell" concept, which focuses the design on an adaptive unit cell with adaptation features representative of the airfoil and subsequently assembles the airfoil through a network of repeatedly linked unit cells. A cantilever prototype assembled with three unit cells is constructed and tested. The testing results show that the prototype is capable of achieving 9.4 degree trailing edge deflection. In Part 2, to reduce the computational cost, a new evolutionary level set method is proposed for design optimization of the typical compliance minimization problems by taking advantages in the formulation of both Evolutionary structural optimization and the level set method.
